While I agree with much of what you say, your "safety" justification confuses me. If someone is wanted for a lesser, non-violent crime, it is arguably safer for the police to knock on the front door, as residents often mistake SWAT teams for armed robbers and grab their weapons in fear for their lives. There is almost zero incentive to shoot a cop knocking on your door unless you are facing decades in prison if caught, the purpose for SWAT raids on non-violent offenders is to prevent escape/the destruction of evidence. If the police were concerned with safety, they would wear chest mounted cameras (proven to reduce assaults on officers), but they actively resist this.
