It's quite likely that Trumps Federal unmarked operatives or Trump's supporters planted the rifle magazines and the molotov cocktails

Why?

In order to drum up support for Trump on Fox News so that he can fire up his base to get re-elected. There is absolutely nothing Trump won't do to get re-elected now including starting a shooting war with China or Iran.

It's important to know just how "out of control" Trump really is at this point. He also is not protecting the U.S. AT ALL from election interference from Russia, Iran or China if you are reading the news lately either.

And if he de funds the post office like he plans, paper mail ballots will not be counted because they won't be able to get to the pollsters so votes can be counted either.

People who are demonstrators would not be stupid enough to leave rifle magazines so this is why the people who left these items are connected with re-electing Trump. And the likely person who shot the armed demonstrator in Austin was in Trump's employ or a supporter of Trump or is one of the Federal secret operatives working for Trump to game the election.

by the way I'm speaking as an intuitive here and as a from birth pre-cognitive psychic.
