I don't equate animals to humans, but cruelty is cruelty! Vick got 2 years in the pen, mugging an old lady will probably get you 10! Being cruel is a willful act no matter who or what animal its done to!
The time spent getting the camera and filming could be used to cut the swing! Have you ever seen a trapped animal that has starved or break its neck? I have! Theres just nothing funny about it!
