This is an example of what might have been a good idea in limited situations ends up totally abused by the government.
And if police won’t use these responsibly, then they should be taken away.
No, they were never a good idea. No knocks are blatantly unconstitutional and brought to us by the War on (some) Drugs TM.
Exigent life and death situations have never needed a warrant, so there have never been any “limited situations” for which they are a good idea.
They are a bad idea made worse by the inevitable government incompetence and excess that always occurs.
