I witnessed one grown man accompanied by two teenage boys (sons?) trap a huge gator (easily 9 - 10 feet) and load it into the bed of a pickup truck. They were a private service requested by the county to remove large nuisance gators.
They clearly had done it before, as were methodical and efficient in their work.
IMO, the problem mentioned in the article was caused by a lack of experience compounded by a lack of manpower. Either that, or the game warden was a second rate piker who didn't really care about doing a professional job. Just because he was a game warden doesn't mean he was a professional or cared about his work.
Well this is Texas... with a saddle of course :)
