The profession of arms comes with fish. The funny thing, this was probably from the neighborhood of SBU 22 which is located with the Stennis Space Center. We don't have annoying fish like that in California. Not even in the Sacramento River Delta. Nope, the really annoying fish are found in the Mississippi River and its tributaries. Thank you Daily Time Waster.
I really laughed when they asked me about wearing body armor on patrol. "The boat is made of fiber glass and aluminum." Still. I don't regret laughing at them.
BLM, EPA, other Game Wardens, would have them in jail for illegal fishing. That's the nature of bureaucracies. Hunting with M2's is proscribed. You should never do it on video. That guy? He clearly gunned a fish. :)
