To my knowledge, no illegal weapons were ever found, and it wasn't from lack of looking. Plus, I have seen video of the holes being made in the wall from exiting rounds when those agents were shot: That fire was definitely semi-automatic. No one was "machine-gunned".
The BATmen raid was stupidity of an unconscionable level. They pulled up in the yard of people they suspected of owning illegal high powered weaponry and started shooting. What kind of response did they expect?
The Branch Davidians were kooks and nuts, but our federal law enforcement agencies showed themselves to be just as bad and far more dangerous.
Every part of that fiasco was handled by people drunk on their own arrogance, and every time they failed they just opened another bottle.
Gee. I thought the BD's had 10 year olds operating 88s, 3 Tiger tanks in the garage ready to go and a 12 year old with a Panzerschrek on the roof.
