 Amid nationwide protests in response to the police killings of Breonna Taylor (who was shot during a no-knock raid) and George Floyd, there were extensive calls to end no-knock warrants.Critics argue that no-knock warrants were prone to lead to deadly use of force by police and the deaths of innocent people.No-knock warrants also conflict with the right to self-defense, "stand-your-ground" laws, and Castle Doctrine which explicitly permit the use of deadly force against intruders.
