If you think this was a crime of passion, where someone JUST HAPPENS to have a pipe bomb in his vehicle, and JUST HAPPENS to have two people in cammo just outside with the same weapon he has, then I got sad news for you.
Yer a jackass.
Seems pretty simple to me. Here’s my theory: Local Muslim ISIS sympathizer works at community center. He plans attacks in advance with his buddies. He attends the party to make sure everything is ready to go. He leaves, maybe shouts something to another attendee. Grabs his buddies who are waiting for the “go” signal. Attack commences.
Can’t explain the pipe bombs though. Maybe they were going to hit somewhere else, or maybe they over-prepared.
Maybe he is just mad that he can’t blame it on a real conspiracy, like the LDS church......
