The OP doesn't mean a real SWAT team -- but the OP is talking about the DHS agenda and practice that puts around more "heavy"-looking agents to put on a show of force like that many people get when seeing a SWAT team.

This is part of a concerted program by DHS to try to "scare the bad guys". It's a dog and pony show meant to intimidate -- intimidate whom, who knows -- more than anything else nowadays.
