enjoyable. and, the third part of that series she reports on what they are playing. you can always keep up-to-date with all the new on our website.

and her son

are part of a rash of shootings. both were shot in the head in unimaginable crime. unless you are steven tabling. >> i see horrible murders. you wonder how can people do this to one another. >> a retired police lieutenant was a top homicide investigator. you worked here for a while. >> i worked. >> out of the western distribute. today he is friends with many in uniform, and he says the police department. and the city's residents are in deep trouble. the last few weeks have been the deadliest year since 1996. >> reporter: what do you think it happening in the city? >> what i think is police are not being aggressive because they are afraid of being arrested. if they make a mistake, they are afraid they'll be charged. >> the strike in crime came a month after the death of freddie

gray a low-level drug offender who died in custody. peaceful protests turned to riots. hundred of businesses damaged. dozens of officers hurt by demonstrators. days later six were arrested charged in connection with freddie gray's death. >> what's the word on the street among the protesters. >> get more time and get out. never in my career have i seep policemen run. when they throw rocks at the cops and they back up i was watching television and was embarrassed. then you see the pharmacy on fire, and a block away there were the police. don't you think they were frustrated they couldn't go. we have never seen that before. >> i hear reports that a number of officers are retireing and

leave the police department. why? >> they are afraid they will not be backed when they do their jobs. >> in my 42 years, i have never been associated with police officers that get up in the morning, put on uniforms risk their lives and say "let me see whose rites i can violate today." >> he is an officer in freddie gray's death. he can't discussion that but spoke about the broader issues facing police. >> i don't think officers get enough credit for what they do. in this city we buried over 100 in the line of duty. i have seen officers working for little money, under adverse conditions with not a lot of thanks coming back. >> on the other hand baltimore protesters express frustration after an aggressive style known

as zero tolerance. in 2000s arrests skyrocketed as police conducted random stop and frisk searches in the neighbourhood. >> stop and frisk peaked when you had hundreds of thousands of people arrested. were all the arrests good arrests. was it over-used? >> it was over used. i never agreed with zero tolerance, i never agreed with that. a lot of people were getting charged for sitting on the front steps and drinking a bottle of beer. it's abuse. you can't abuse people. >> seems like there's a fine line between aggressively policing things that can be proactive, and on the flipside if the policing is too aggressive it breaks down country's trust in the police. >> there's a line between being too aggressive and being aggressive.

if stop and frisk is done properly it can harm nobody as long as the officer doesn't just go up to corners and pad people down. anyone can make an arrest. anyone can't carry it through to get a conviction. >> coupled with stop and frisk, in the late 1990s, baltimore used a program called comstad. a statistic tool that critics say encouraged officers to overarrest people if they had numbers. >> if you look at the police department it's a numbers game. >> former baltimore police commissioner oversaw the compstat programme, hoping he says to save lives. >> i said this publicly i got here with 320 murders. that was the average. that is still so times the average. i felt if this was a majority

city people would be up in arms. no one cared. >> reporter: norris said compstat was misused by his successors who took zero toll wraps policing too far, and he is not to blame for the tactics under fire today. >> we targeted minor crimes. if you had a series of shootings or murder you can't stop them. it enforced laws. people have the bigger crimes it was the way it was done. post that after i left they were pushing minor laws but not with an eye towards solving bigger crimes. it created a lot of animosity. on top of pressure for unless the retired lieutenant blamed police trading for the distrust. until a few years ago he appeared at the academy.

>> i had a guy at the police academy. know what he said to me. you worry too much about the law. >> so you have officers on the streets that don't understand the law and constitutional rights. >> if they better understood the war they'd be making better arrests and be able to evaluate situations when they came on to the scene instead of acting out of frustration. overly aggressive policing poor legal training a bad recipe according to training decades in the making. leading to baltimore. sky rocketing crime, a police department demoralized. right now they are in a bad position. i told recruits you are getting into a thankless job. if you think someone will pat you on the back you better think again. >> great thought there.

"america tonight"s adam may is here. i know you well connected, you know the community well. what are the officers telling you on the side behind the scene? >> i talked to half-a-dozen recently retirement police officers over the last couple of days, and a lot are echoing the sentiments of the president. one off-duty officer says it is alarming and she was responding to a 911 call where someone was reporting drug activity in the neighbour hoot. when she turned the corner people were waiting with cellphones and felt they knew they were coming. the police have so much mistrust going back to the citizens they are not sure if the calls coming in are real and wonder if people are standing there with cameras. she didn't stop the car, she said she continued on through the neighbourhood and didn't see anything. that is indicative of what is

happening. >> and what the order of police is telling you. >> yes, they put out a statement. i have never seen anything like this coming from police departments saying criminals feel empowered, police are under siege on every quarter and officers are more afraid of going to gaol tore doing their jobs properly than they are of getting shot on duty. officers are more afraid of going to gaol than being killed on the streets. a couple of days ago the police commissioner took a lot of heat from the rank and file officers. he met with some people and recorded part of that meeting. and in that almost an apology for the relationship between the administration. >> talking to the retired lieutenant. was he able to give you perspective. was it always this way? >> no he talked a lot about the

good old days he was a retired cop. there were days he would walk around the neighbourhood. if you wanted to solve a crime, they'd go to the store. >> the foundation. >> the buzz words, community policing. what he told me about was early in his career he was involved in a police involved shooting himself. he pulled the trigger and a man died. what happened to him is so different right now. he immediately had to turn in his badge, he ended up in court and he had to defend himself. a lot of people had to make - officers used to go in front of a judge and defend their actions. >> they didn't have to wait through it process as we see today. >> "america tonight"s maya angelou. >> next a medical device used on hundreds of thousands of

patients each year now connected to a deadly outbreak. what could have stopped the superbug. hot on the website - gaol house and a scandal sending an innocent man to death, and an accused killer on to the streets. listen to the recordings of an informer ring at

aljazeera.com/americatonight. now our fast-forward look at the super bug. they are dangerous, hard to kill and easy to spread. coming up in hospitals across the country, and there's fear that it could be connected to a device used in hundreds of thousands of procedures. michael oku vets the evidence. the danger could have been prevented. >> reporter: biomechanical engineer has been tracking sometimes uncovering the outbreaks for years. this is what he thinks is the source an endoscope. it has a camera and placed down the throat of a camera. according to the f.d.a. scopes are used in about 500 procedures a year. the hospitals involved in the

outbreaks pointed to the endoscopes as the source of infection, saying they are hard to sterilise. infected patients had e.r. cps. between october 2014 and january 2015. another 129 may have been exposed to the super-bug while undergoing the procedure. tens of thousands of the procedures are performed around the world. we've not had multiple clusters of patients who are developing the super-bug infections. we know that the cleaning protocols can work and be effective. >> the attorney is representing two patients infected at u.c.l.a. he is suing the maker of the scopes alleging fraud and product liability. the lawsuit says olimp us didn't

provide effective cleaning protocols when it rolled out its latest version of the device. >> do you say there's a design flaw? >> we are early in the investigation. it appears what's the tweak was made to vice something olimp us described as a redesign without the cleaning protocol. if that happened olimp us was asleep at the wheel. >> in seattle investigations by public health officials and the c.d.c. found problems with keeping the scopes clean, even when the manufacturers cleaning protocols followed. the follow statement was given to "america tonight" saying their product requires attention to cleaning and reprocessing stents including manual

recleaning. they told us they'll work with the f.d.a. records show that the f.d.a. knew about problems with dirty scopes for years. in 2009 the agency issued the safety caution. it found it difficult to clean. it provided health care facilities with recommendations to deal with the risk. >> reporter: when a drug is used and it's harming people and it's rich to the level it has today. action needs to be done. it should have been done last year years ago. fast-forward now to a super-bug under the legal microscope. the u.s. justice department now getting the largest manufacturer of the scope, called olimp us and its devices used at u.c.l.a. and other hospitals seeing the

we have chronicled the dramatic surge in heroin use in places you would never expect. suburban neighbourhoods and world communities too. snack is cheap and it is killing. the flow of the drug into the country is growing. oncompass with sheila macvicar we trail it from mexico into the united states. it's something he would not consider carefully, where the drug it coming from. >> it didn't use to come from mexico. that makes the drug cheaper, easier to get to the united states and u.s. officials are overwhelmed in the amount of

material that is being moved, the amount of material coming into the country. the people that were selling heroin know where the market is and know that their markets are in mostly small towns. towns like west virginia. >> martinsburg, west virginia coming into small communities, places that we thought were fairly insulated. >> well according to a study published in the journal of american medicine the average hero wix, h 23, and living in a suburb. that is a dramatic change of of the epidemic of 20 years ago. but it is killing at an astonishing rate. 2013, 23 people died because of heroin every day in this

country. >> 23. >> every day. >> and the trend is going up. it is not an epidemic that is slowing done. it is an epidemic at the soul of america. >> it has to be a growing challenge in law enforcement. this is not what you have to deal with at a place like this. >> we talked to the head of u.s. customs and border patrol. he was the president's drug tzar. he was with the police in seattle. this is the man on the front lines of the drug war, one way or another for all of the career. this is a war that america is losing he says. it's not enough to say. it's time to deal with drug addiction. he says as a mental health issue, as an addiction issue. it's the resources that you need

to deal with treatment, treatment beds. that is what is going to stop the heroin epidemic we'll look at what is done to cut off heroin at the border. this doesn't, indepth report the tracking of heroin and on a subject that nose no borders, a mastermind - ross ulbricht created and ran the silk road site on the net giving users access to illicit drugs and products. lori jane gliha found a multimillion black market business. many defended it as a safer way to use drugs. >> reporter: the first time you logged on to the dark web to buy drugs, how nervous was you? >> i was pretty nervous.

>> this woman was 15 when they started to buy drugs off the dark net. and asked us not to use her real name? what was the surprising thing from the dark net that surprised you? >> you could order drugs anywhere in the world and they could be delivered to your doorstep. >> by using a browser, she could access sites visible to search engines where the illicit drug trade is thriving. here she ordered everything. like other users, she made most of her purchases on a site called silk road. >> as soon as you log on you see images of all kinds of drugs. like just right at your fingertips. >> then in october 2013 the fbi seized silk road and arrested its mastermind. ross ulbricht.

>> he saw it not as a money making scheme but a new epic in the history of mankind. >> reporter: the first journalist interviewed ulbricht by email before authorities arrested him. >> he had this kind of libertarian, anarchist approach. >> reporter: his business approach was so popular it drew buyers and sellers from all over the globe. a purchase was like amazon.com. they searched for the drugs and put it in a cart. they red reviews. >> it's safer. online goes on the website. the product and the vendor's

description of it. it's what the customers say about it. rather than giving you the industry you can hear about it. but you don't really know. >> as much as you say it's safer, you never will know who sold you that drug there's never someone to be held accountable. >> that's true. if that turns out. in effect it's all at least people that there is no trace that can talk about it. chances are someone brought a drug from the vendor if they are a popular vendor. >> the perceived safety had been an argument in ulbricht's defense after a jury found them

guilty of felonies carrying a minimum of 20 years behind bars. ulbricht said it was to help people make their own choices, but turned into a convenient addiction. >> ulbricht never advocated for the abuse of drugs. >> prosecutors used details of six drug overdose deaths relating to silk road users. they say they will not stop the online crackdown, and it's a matter of time before others are also brought to justice.
