There is a middle ground between, for example the shooting of Tamir Rice, where the officer shot and killed this innocent 12 year old boy before his police car had even come to a stop, and Uvalde where police stood around for an hour. Police should take time to observe the situation (this could be 30 seconds), take cover a safe distance away (this was not done with Tamir Rice), confirm the threat is real, attempt to de-escalate, and shoot only if necessary. We see in many cases police burst on to the scene and shoot almost immediately, and this leads to unnecessary death.
