I think you misunderstood me. I'm not making excuses for them; there are places where police will react differently to a disorder just because of the nature of said places. You don't fuck around in a nuclear plant, you don't fuck around in a train station, you don't fuck around in a hospital and you don't fuck around in an airport (to name a few). Because in places like those, police will prioritize the general safety before that of those fucking around. Sure, the police will then be investigated to see if excessive force was used, but in certain places, it's better safe than sorry.
Even if the police is found guilty of excessive use of force, these idiots fucking around in an airport are still dumb as a sack of rocks.
