If you think that the concern about DEA and SWAT can be easily dismissed, consider that SWAT teams regularly get involved in serving warrants for non-violent crimes -- in 1995, 3 out of 4 SWAT raids were based on drug warrants alone... and mistakes on those warrants can be made repeatedly:

"Perhaps no one was more victimized by the battlefield mentality that had set in at the NYPD than Walter and Rose Martin. The Brooklyn couple, both in their eighties, were wrongly raided more than fifty times between 2002 and 2010. The couple filed numerous complaints with the police department. They wrote letters to Mayor Michael Bloomberg and NYPD commissioner Ray Kelly. They were ignored. In 2007 they at least got someone at the NYPD to try to wipe their address out of the department’s computer system. But the raids continued. It wasn’t until the couple went to the media in 2010 that the city finally looked into the problem. Back in 2002, someone had used the Martins’ address as a dummy address to test the department’s new computer system. When the new system was implemented, no one removed their address. So anytime NYPD cops in certain precincts used the system for a warrant and forgot to remove the dummy address to put in the correct one, the police would end up at the Martins’ door."[1]
