stochastic terrorism

Is there non-stochastic, predictable terrorism?

How do you know what was the purpose of the attack? I can't find anything in the media on his goals.

which is why constant shocks of stochastic terrorism have helped increase police budgets in a time period where no one trusts the police and considers them a government-sanctioned group of thugs who will lie, cheat, and steal to ruin your life.

OP is not in USA.
