Actually, we watched a drug raid some years ago in the welfare, absentee slum lord house next door in the welfare pit we used to live in. It was pretty tame. The cops walked the guy out in handcuffs, then walked through the house, looked at stuff, left the mother (arresstees mother)and little kids (daughter nad nieces) alone and I simply cannot recall whether they had shotguns or not.
Handguns were ALWAYS visible but I don't ever recall seeing shotguns, and there was plenty of other police activity we saw in the 18 loooooong years we lived there.
I should count my blessings that I'm not more familiar with what police carry routinely.
