Hmm...the book The New Jim Crow: Mass Incarceration in the Age of Colorblindness is talking about these SWAT raids. It sounds like most drug related search warrants need to be conducted in this fashion. Collateral damage (property destruction, deaths, emotional or physical trauma) does not seem an uncommon outcome.>Should it illegal for police to conduct no-knock raids and night-time raids?
If the collateral damage were greater than the benefit to society of locking up drug offenders (that couldn't be discovered without a SWAT raid) or if the collateral damage were simply intolerable no matter the benefit, you could say that. Although I'm becoming confused about the relationship between legality and police action.
