When I worked with Local, County, State and Federal LEAs in my home state I was always curious why so many small towns created SWAT. Even with great training, one has to have a large gene pool to draw from first. Michaelangelo spent much longer looking for the perfect block of marble than he did actually carving the David once he'd made his selection.

Most communiites would be better served by having 1-2 guys who train with a larger city SWAT, who can act in a pinch as shooters, or more likely as liaisons to facilitate bringing in the main team once needed. The lure of black velcro is strong, though, and everyone wants to be a cool guy...
