One of the major points of warrants was to insure that the resident/homeowner would *know* that it was an official investigation and not just a robbery in progress.
The whole process is pretty much invalidated by the “no knock” policy. There are very few criminals who deliberately want a shootout with the police. That is almost never the case. There are probably more shootouts over mistaken identity than deliberate shootouts with the police.
If anything, police are more routinely killed on traffic stops than serving warrants. Does that fact now mean police, can force people off the road in unmarked cars(or with one little siren that people can buy on the internet on the roof) and pull them out of their cars?
Of course not. I also find the excuse of ‘possible presence of firearms’ to be beyond dumb. It’s the USA. Other than a few liberal hellholes, what place in this country is it NOT POSSIBLE for law-abiding citizens to be armed (not that it ever stops criminals anyway) and how often do criminals get involved in firefights with police when they suspect there’s a police raid?
If anything, EVEN CROOKS would be more likely to open fire and hurt police, if but for the fact that the ‘surprise’ element means there’s an element of the unknown to them and they are aware that people pose as police to get at the drugs and money.
So it doesn’t even make sense if one applies the logic of the police.
