This is how to deal with those who deliberately take over public spaces or block traffic screeching "Death to America!". Bring out the Riot Control Scoop Loaders, scoop up the garbage and cart it off to a landfill in the Gaza Strip.
The scoops were an interesting part of the movie for riot control, but the more terrifying riot control tactic that was used in the novel by Harry Harrison was "flying wire".
Razor wire concertinas made of an incredibly strong tempered and compacted spring steel. When dropped in bale form from a helicopter, it exploded on impact with the concertinas blasting out at high speed picking up anything in their path. It was used to quickly seal off streets.
