People need to keep in mind that the DHS also now includes the US Coast Guard. The USCG needs those weapons for drug interdiction, combating piracy etc etc.
USCG
I truly think they are not intended for use against Citizens.
Personal Defense Weapons fill a niche. They’re a compact weapon that packs a bigger punch than a pistol, especially in close quarters situations (clearing rooms, the back of a crowded APC, etc).
DHS and its components have a requirement for a 5.56x45mm NATO, select-fire firearm suitable for personal defense use in close quarters and/or when maximum concealment is required.
