You can blind someone with a fork, but if the feds arrested you while you had one in you backpack and claimed you were carrying a weapon, that would be a ridiculous mischaracterization.

I can smash your head with a MacBook Pro and it might cause you life threatening conditions. Does that mean carrying a MacBook Pro is a weapon?

So can rubber bullets and tear gas canisters. Can't expect the government to act lawlessly and there not be pushback.
