"Police Don't Know How To De-escalate : Officers "too
often fire their weapons in a manner and in
circumstances that place innocent bystanders in danger;
and accidentally fire them, sometimes fortuitously hitting
nothing and other times shooting people and seriously
injuring them. CDP officers too often use dangerous and
poor tactics to try to gain control of suspects, which
results in the application of additional force or places
others in danger. Critically, officers do not make effective
use of de-escalation techniques, too often instead
escalating encounters and employing force when it may
not be needed and could be avoided."
