Animal welfare group pressures grocers with videos

The AP reports:

An animal welfare group that has used undercover videos to generate public outrage over the treatment of livestock said it now plans to use secret recordings to pressure large grocery chains to stop buying from farms that use practices it considers abusive.
The effort seemed to be working as several chains viewed the video and then either halted purchases from the targeted Iowa hog farm or expressed concern even before Chicago-based Mercy for Animals formally unveiled the recording at news conferences planned Wednesday in four cities.

When animal rights groups go "undercover": they are heroes. When Andrew Breitbart does it: it's called "provocative".
