we're going to show you photos from port arthur, texas. this is what it looks like where there is a playground where this stuff, this filthy, dirty stuff is burned. this is not a good place to be. we had people at a press conference with the nurses from port arthur, texas, and they brought us these pictures and said this is what it's like when they burn the tar sands. now, let's talk about the types of cancers that are linked to these types of chemicals, including leukemia, non-hodgkin's lymphoma. why would anyone want to short circuit a process? just because the oil companies want it? we've got to think about our people. tar sands oil from the keystone pipeline will flow to our gulf refineries, increasing this toxic air pollution that already plagues communities like port arthur, texas. i ask you to meet with some of those kids, meet with some of their parents, meet with some of those health professionals and they will tell you the asthma rates that are happening, the respiratory illnesses, the skin irritations, the cancer. all they talk

watched every other country high income country like us, most recently aus trailial in 1996 after the port arthur massacre who was on a similar path to us, they have not had one mass shooting since then even though they had 11 of them in the ten years preceding that. it's not a mystery. we have the national rifle association who in service of who their real clients are, which are the gun manufacturers that make millions off of selling military style rifles and military style weaponry to people, they don't want any regulations so the nra goesz to bat for them and comes up with false justifications for why this has any relevance to the second amendment. we've got kids walking around either mentally troubled and right wing people with far right wing politics like those who shot two police officers in las vegas, execution style, and left a nazi swastika. and it will keep happening if we don't do anything about this. >> cliff, for people at home and parents watching this right now, wanting it to be not one more, one of the hash tags that's gone viral, what can they do that you think will be politicall

those actions by australia's leaders made a difference, and a decade before port arthur, australia saw 11 mass shootings. since then, there hasn't been a single mass shooting, and the gun murder rate has continued to steadily decline. in 2011, australia had 0.86 gun deaths for each 100,000 people or 35 -- or 25 people. that year, the u.s. had 10.3 gun deaths per 100,000 people or 11,101 americans. mr. president, so accounting for the population differences, this is insanity. australia said enough is enough. when are we going to do that? canadians said enough is enough. in december, 1989, a disgruntled student walked into montreal engineering school with a semiautomatic and killed 14 students, injured over a dozen others, and in canada, they now ban more than half of all -- let me put it this way. that tragedy prompted the leaders in canada to ban more than half of all registered guns, require all gun owners who must be at least 18 to obtain a license. you need a license for a car. why don't you need a license for a gun and a background check? and a public safety course. that's what the

australia, 1996. 35 people killed and 21 wounded in the tourist town of port ar arthur. just ten days later, the government announces a badge on semi automatic weapons and a massive buy-back program. lawmakers say it worked, gun deaths plummeted and mass shootings stopped completely. >> we had one in the decade beforehand, we didn't have any in the decade afterwards. we have also seen big falls in gun homicides and gun suicide too. >> but in the u.s. after shootings in virginia tech, aurora, colorado, newtown connect, gun laws have largely remained unchanged. and while everyone agrees, the laws neat improvements, most say the access to guns. sort by country, mental illness and weapon. and as you scroll through the decades, you see more and more red, almost entirely in the u.s., red means an automatic or semi automatic weapon. >> in your ambition is to -- if your ambition is to kill a whole bunch of people, very difficult to do with a knife but for a mentally disturbed person to do with a semi automatic weapon. >> most are not violent and mass shootings are extremely well

australia had the port arthur massacre, like our new town where 40 people or so were killed.ny other injured. what did they do? they passed a series of strict gun laws. they had 11 mass shootings in the ten years before. they have not had one since. the suicide rate has gone down 70%. the guns with homicides have gone down about 70%. we have seen it in england, france and canada. canada and australia had that same frontier history as us. we are willing to look at this as a public health problem like drunk driving, second-hand smoke and regulate it in that manner which is to say some people should not have access to guns. we should have universal background checks, psychological tests. people should have a few family members vouch for them, which is what most other countries do. family members knew that these people were in trouble and didn't want them getting their hands on guns. we can do this. every other country has done it. we have the powerful lob by and kourds in congress who are stopping us from doing it right now. >> cliff scheckter, thank you so much for sharing your
