That's not true in the 80% use case of SWAT teams which is drug offenses and executing search warrants. This is the core argument for demilitarization, not the straw man of "I don't want police to have the equipment needed to respond to school shooters." Showing up with militarized teams to mostly non-violent situations just causes escalation after escalation and is why militarized units kill at a far higher rate than just the police alone.
