Again, Trump had nothing to do with his anger and rage or tendency to murder. Just like guns, people seem to like to point to "something" in response to incidents like this because violence, murder and insanity are in all of us but thankfully as individuals most of us can control those things but they aren't something you or others can take away or control. So given that the response is to try and remove or blame something else. How's that working? Trump isn't their President and AK's are not something they can easily get if at all legal.
In the end it may give you comfort to blame Trump but it won't do you any good.
