This was not my experience. In the Honolulu office everyone except the guards were wearing aloha.
From crossing the border between the US and Canada regularly both US and Canadian officers are equipped with gear and armed. They are likely Bulletin Proof or Stab Jackets. You really never know what is going to happen
Wish I had a bulletin proof jacket...
It's a perk of the job, but only if you understand how they see their jobs...
