We've had a few instances of buffalo escaping from a local meat packing plant. Let's just say the local PD's tactics are evolving.
P.S. Sorry for the link to the HuffPo.
http://www.huffingtonpost.com/2012/02/02/colorado-springs-escaped-bison_n_1250589.htmlIn an incident now known as the 'Great bison massacre of 2005,' five of the animals -- each weighing close 1,000 pounds -- escaped from the G&C meatpacking plant in western Colorado Springs. The creatures holed up in a nearby backyard where officers, afraid the animals could spook, stampede through the city, and hurt bystanders, decided to put them down.
83 bullets and approximately $30,000 in collateral damage later (no one was hurt), officers realized their .223 caliber bullets didn't have the oomph necessary to do the job safely and effectively. CSPD learned from the incident and updated their response policy accordingly.
