Obviously, it's a terrible situation and you can't even begin to describe this with words. Special respect to the police and law enforcement for doing an AMAZING job in minimizing this the best they could. The mainstream is so quick to jump on the police but when things like this happen, they get NO respect.
I do have a very cynical view on the aftermath of events like this, because it's really the same cycle each and every time something like this occurs:
1. Tragedy happens, whether natural disaster or caused by scum.
2. Everyone will update their status on Facebook and/or Tweet the EXACT same thing (you know what it is).
3. Celebrities and social justice warriors will blame the President. Doesn't matter who it is. Happened with the previous administration, the one before that one, and the current one. Yeah, that'll solve things.
4. Families of the lives lost will mourn and pay their respects to the ones they lost, and those that survived will never forget this horror. The social justice warriors, meanwhile will continue to blame the President and politicize it. For a few days, then they will move on and forget.
5. The warriors will continue to scream at the guy in the White House on, yup, social media. Not realizing THESE are real issues that need to be protested. Actual protests, not just updating your social media or posting pictures of yourself.
You can't even begin to tackle these sorts of issues when the people don't have their priorities in order.
