Both sides have rotten apples but this election cycle we are seeing violence from the left that we are NOT seeing from the right. Just like when your BLM supporters assassinated police officers.

when did they assassinate police officers?

The leftist terrorist group, Black Lives Matter, has been recognized by the Democratic Party and even attended the White House to meet the president: http://thehill.com/blogs/blog-briefing-room/news/287593-prominent-black-lives-matter-activist-to-attend-obama-meeting The president of our country and attorney general have said that BLM protests are a good thing and they've even sat in at a forum with the president about policing in a America: http://www.cnn.com/2016/07/13/politics/obama-black-lives-matter-meeting/ During these BLM protests, which Obama publicly endorses, signs are seen with slogans like "Oink, oink, bang bang!", and chanting "What do we want? DEAD COPS!": http://www.dailywire.com/news/7537/11-worst-anti-cop-signs-black-lives-matter-rallies-aaron-bandler Finally, in Dallas, 5 officers were killed and 7 wounded at a BLM rally and protest: https://www.google.com/amp/www.nj.com/articles/18914228/4_cops_killed_7_wounded_at_dallas_black_lives_matt.amp?client=safari

first of all, signs do not equal action. someone may want something, but recognizes the ethical/ legal consequences. also, the cops murder at a BLM event was not from seeming in the BLM movement, and BLM does not endorse it. there were protesters taking pictures with cops and having convos, not being aggressive. the goal is to unify, that's why it's Black Lives Matter (too). that's the whole point. anybody who takes advantage of the platform for their own agenda does not represent the movement

Excuses.
