I don't know why politicians are wading in to the kyle issue.
The fact is, he shouldn't have been there. The 'protestors' (rioters) shouldn't have been there and they definately should never ever ever have approached a guy wielding a fucking rifle, let alone threatening him, let alone doing it to kyle (a kid). In this situation that shouldn't have ever happened, he defended his life against guys much bigger and older than him, one even brandishing a fire arm.
What angle do the politicians have to gain from this? They'll piss off more than half the country, who either agree with gun rights, defense rights, defending your community, or will now see that what they were told in the MSM was a load of old arse. They'll piss off everyone who believes in the justice system and piss off anybody who agrees that rioters shouldn't be burning shit down on a whim.
None of that is a good idea while your approval rating is in the toilet. A simple "The greatest justice system in the world, along with X jurors from the free-est country in the world, found Kyle not guilty of murder. We should stand by our court systems, whether we agree with the outcome or not, because it's part of the reason why our country is great/ace/numbah wun". and leave it at that.
America needs Trump, or Trump-like pride more than ever.
