Y'all as bad as each other. It's not unusual for additional resources to be made available in times of crisis. We live in a state where not only will a person get a bullet in them for a traffic stop, but organised crime syndicates will descend on a single police unit for the simplest of crimes.
Couple that with the trigger-happy nature of some of our police service, and it's not really surprising that the police are coming out in force to round up and control the criminals and people are getting wary.
The answer isn't more weaponry; It's for organised crime to be more subtle/covert to avoid being caught by police, and for street gangs to reign over their small areas without the support of random other factions.
We're not in goddamn Gotham City!
