they did that after close of business on friday. there are 16 of them in total and it's security camera footage that's on the videos. we've been calling the baltimore police for some kind of comment and they've yet to respond. al jazeera america has trolled through 16 videos. they don't appear to show very much to the untrained eye. at one point it appears you see a suspect on the ground. it appears that he might be arrested by police officers but the pictures are really quite grainy and without expert knowledge it's difficult to see what's going on. we did hear from sr. senior police, in the course of that we learned more about the ongoing status of the investigation into freddy gray's death. late friday afternoon news conference by baltimore police the probe into freddy gray's death honing in on a gap the day he ran from police officers.

>> there's a gap for me. the gap between where mr. gray ran from officers and where the video picks up. what we don't have there is witnesses or bcc pictures. >> the weekend is here and the weather forecast is good. baltimore's mayor aware that tempers may flare is calling on protesters to remain calm and wait for the investigation to be completed. >> i understand when there is a situation such as this. there is often a desire to say you know, somebody's got to pay. someone's got to go. it's not that i don't understand this sentiment. this is a horribly tragic incident and i'm determined to get to the bottom of it.

>> the protesters want that process speeded up and for baltimore's police chief to go. he's determined to implement changes throughout the force. >> we ended up walking away, praying together, standing together. i made a promise to them that we will continue to change this organization change the culture of this organization, i'm driven by making that happen. >> the commissioner says, organizers plan a shutdown of the entire downtown. >> we're saying that justice must come and you're not going to come out here and try to flip it on the demonstrators and they have suffered too long and that's why they will be taking a stand on tomorrow. >> reporter: some city officials are concerned the event could get out of hand. a phrase people outside of baltimore could come in and stir up trouble. simply can't happen in the gray

case. the law of the land must be allowed to run its course. >> if you really want justice for mr. gray and his community and the police community we should not let information be released, there will be no case even if there should be. >> reporter: now all police leave cancelled. they hope they don't need them. >> to any and all that would seek to bring chaos to our city, the people of baltimore will not tolerate you hurting our community. where we live. where we worship. where our kids go to school. >> reporter: now i'm live outside the police station in west baltimore in the neighborhood where freddy gray lived. as you can see it's pretty quiet this evening antonio. it has been the scene of protests the last couple of nights. we think the protesters are getting a good night sleep before the day tomorrow.

american life. we all grieve when any innocent life is taken. we don't take this word light. and i know thatly.i know each and every one of you understand the magnitude of what we do and the stakes involved and these aren't abstraction he and we are not cavalier about what we do. >> italy is demanding more answers about that drone strike that killed two al qaeda hostages. italian aid worker giovanni la porto and jeremy winestein. said his country needs much more information about what went wrong. italian authorities have arrested several men suspected of plotting an attack on the vatican. nine men were detained in raids

across italy and prosecutors say they are looking for several more suspects. the men under arrest are also accused of carrying out and financing attacks in pakistan and afghanistan. claudio lavongo has more from rome. >> on friday, italian police conducted a nationwide major antiterrorism sweep that led to arrests of nine people, seven are believed to have returned to pakistan already. now all of them were pakistan afghani nationals who moved here in 2005. they blended in with local communities, some of them were business men well regarded but behind the scenes, investigators believe that these people were raising funds to finance terrorism operation. back in afghanistan and pakistan and took part in some

attacks, including the bombing in peshawar which killed more than 200 people. people were believed to have had close ties to the network that protected osama bin laden two people were asking about his health in particular. but the most shocking revelation perhaps was that investigators believed that this network was organized some kind was planning some kind of attack to the vatican at the time when pope benedict rm 63 was still in xvi was till in office. that was a long time ago five years ago and nevertheless, italy and the vatican included are still targets of targets of organizations such as i.s.i.l. and the threat is very high.

christian armenians killed by ot ottoman turks. los angeles armenian march protesters demanded the turkish declare it a genocide. proturkey demonstrators threw objects into the crowd. president obama marked the date but for the seventh time in his term of office. >> too long that the government of the united states and the government of turkey have denied the truth of the armenian

genocide. >> the facts are not in dispute. the systematic slaughter of 1.5 million armenians by ottoman turks who ruled over them. the modern day turks have made it clear. >> what they don't do is call the g word, the genocide word. they have this allergy to the word genocide because of its association with the nazis and with the idea that it is the ultimately evil crime. >> if the u.s. used the g word it would risk enrageing turkey, the pope said it and so has the german president and the eu. one leader has not crossed the line even after as a candidate for president vowing he would. >> for those of you who aren't aware there was a genocide that did take place against the

armenian people. >> reporter: as president mr. obama promised he would say the g word but he hasn't. he's not alone. every other president since reagan has also shied away for fear of angering turkey a secular democracy in a volatile region. turkey is home of the incirlik air base, armenians and their supporters say it's more about geopolitics or mere semantics. >> that we will not speak the word genocide even though that's the word for exactly what happened to the armenian people because we don't want to offend an ally. that is i think a far from courageous stand to take on a seminal human rights issue. and it's not something america can be proud of. >> reporter: friday, turkish supportsers in washington had

their own protest. >> let's look at the broader tragedy that has occurred to both muslims and armenians as the ottoman empire fell apart. >> survivors of the genocide, so it really pains me, it angers me it frustrates me. >> for armenian americans another year without the recognition of the suffering of ancestors. mike viqueria, al jazeera washington. >> a liker captured this video when the calbuco volcano erupted wednesday. some ash has spread as far as buenos aires. >> as you can see calbuco is still huffing and puffing behind me. the question is whether it is going to blow more houses down

like the restaurant you see behind me. it collapsed under weight of volumevolcanic ash and stones. everything here is covered with volcanic ash and stone. 400 people have been obliged to evacuate authorities have allowed some people to come back through the course of today to check on their animals to try clear the roads to their houses. it is quite amazing this scene here. the ash is very very thin, you can't see it but it's in the air. most people are wearing these masks like this to avoid breathing disorders. that's the thing the authorities are most concerned about. but the real problem we don't know when it's going to end. this explosion there haven't been major eruptions but the size moalings said there could beseismologists said there could

court reporter for atlantic monthly. this case is different garrett it goes much further. at first one of the issues before the court is whether the constitution specifically the 14th amendment should be interpreted as requiring states to allow same sex marriage? >> absolutely. the two questions are: does the 14th amendment require a state to recognize out of state same-sex marriages and does the 14th amendment require a state to perform those marriages itself. >> and the second question, whether it needs to recognize same sex marriages could pose a bigger issue for conservative justices right? because aren't they stuck between two principles, conservative allegiance to conservative principles and strong adherence to state's rights? >> it is the case but the last two important victories for gay

rights both involved state laws. and the court majority had no hesitation in saying the federal constitution and the bill of rights and the 14th amendment overrides state laws against gay sex or against -- or pro-discrimination against gay people. so it's entirely predictable or seems likely that there will be five votes to do the same in the marriage issue. >> and so you think it will be likely that we will see a repeat of what's happened because of those prior rulings that we will see a 5-4 decisions on both of the issues? >> the most likely outcome most people agree is a 5-4 decision with an opinion by justice kennedy that will say that states have no good reason to refuse same sex couples the right to marry and the recognition of their marriages. there could of course always be a surprise. but the smart money is on the 5-4 victory for same sex

marriage. >> do you think john roberts the chief justice who at times has been a bit of a maverick when it comes to obamacare he has a lesbian cousin. do you think that would affect his decision? >> you know, i think the chief justice is a man of very conservative principles and he really decides based on those principles. i don't think it's my understanding his relationship with his cousin is fine but he is tremendously responsive to the concerns of the states. and he is tremendously responsive to his own religious faith and religious values. i would be very surprised to see him only two years after his dissent in windsor i would be very surprised to see him cast a vote the other way. it could happen. he does have the capacity to surprise but i don't expect it. >> if the court does rule as expected what will it mean? >> welt, what it will mean is that all the couples in the 22

states where federal courts have ordered same-sex marriage to be performed, those couples can breathe a sigh of relief. their marriages are now secure. those states will continue to off same sex marriage. the states that have refused who are trying to obstruct it are going to face some fairly sharp litigation same sex marriage, alabama and texas and is the other states are going to be in court within minutes. and there's going to be a series of cases testing whether marriage equality really is equal. whether in matters of foster care matters of adoption, matters of public accommodations the states will protect gay marriages. >> and the decision will come down probably in june and we'll see all those other cases i'm

sure in the future. garrett epps good to see you. thank you. er visits have jumped nationwide by users of a synthetic drug spice. >> alabama law enforcement officials say their state is under siege plagued by a synthetic drug known as spice that in recent weeks have contributed to overdoses in tuscaloosa and officials got this bad batch in montgomery. >> as we have seen in this case across the state it is poisoning our children. >> there were a thousand reports of adverse reactions to spice. nearly double the report from january through march. thursday alone saw 172 cases. officials blamed the issue on

the powdered forms. >> we have seen those in blotter paper like lsd or acid from years ago we've seen blotter paper with that. >> it's leafy spices are sprayed with acetone. >> they are coming in psychotic very difficult to control and very violent. persons have fast heart rates low blood pressures very dangerous things. >> adding to the rising use of spice, the sucialg in surge in vapping. in high doses with dangerous consequences to the heart and kidneys. most of the drug seized by dea

>> 25 years ago today the first space based telescope was

launched into orbit. since then, the hubble telescope has captured scenes never before seen. >> in new york city's times square this week, the visitors are getting a real time display that is far far out thanks to the hubble telescope which launched in 1990. from its orbit the instrument has sent back 1.2 million observations. by hovering past the earth's atmospheric haze, likened to seeing a pair of fire flies in japan all from the east coast of north america. scientists have gotten their most accurate look at planets from the solar system anfor the first time identified places beyond it and they have wanted a deeper appreciation of the immensity of space. >> we now know thanks to those

deep filled images, there are now hundreds of billions of stars. >> the universe itself tracing it backward in time to places 13 billion light years from earth. >> the galaxies are not only flying away from each other but they are accelerating. filled with energy astronomers call dark energy. >> in 1993, a fatal flaw discovered in its largest mirror almost made it worthless but nasa dispatched a crew that corrected the error. hubble is expected to keep operating for a couple of years but an instrument 100 times more powerful the web telescope is due to be launched in 2018. >> and the two operating at the same time so that will open a
