Voting machines are far easier to hack than human processes, and there have been numerous presentations on this particular topic.
American politics being off the deep end is an entirely different topic.

They do not want to confront trash bag man for good reason. What happened is people who don't give a fuck and have no problem with using violence realized there's nothing stopping them from loading up bags of goods and walking out of the store. "Oh you want to stop me? just try mother fucker." Even so called security guards want no part of trash bag man because there is a high chance of violence and most humans do not want to engage with that. Never mind these guards are paid very little and are nothing more than security theater. Pull a gun and those guys are going to be no more a guard than the cashier or a person in line.
The stores are left to fend for themselves as cops these days seem to care less and less. So I am not surprised they are employing all sorts of janky tactics to prevent loss.
Point being, willingness to engage in violence has nothing to do with it.
