I WAS WRONG.
I downloaded the highest-resolution video of the Coast Guard intercepting the semisubmersible smuggling vessel, and the helmet does NOT have a SEAL trident.
It's a discolored American flag decal that's peeling off.
It appears that these men are members of a US Coast Guard Boarding Team.
I’m not surprised. I worked for USCG and know how well trained they are especially before going overseas. They are awesome.
Those who label words as violence do so with the sole purpose of justifying violence against words.
