Sounds like they found a patsy, followed him, pulled him over near "Democrat Headquarters" whatever the fuck that is, found the machete (perfectly legal especially if you are on a road trip and camping and shit... even if not this is America you can carry whatever the fuck you want in case you need to defend yourself wtf) anyway, they find the machete and realize they can't really make any charges stick so they plant the "bayonet" because that sounds scary and will guarantee prison time and the pigs had it under their car seat, waiting for the right time to use it and this seemed like a good time.
