"shoot a school kid"

LAS VEGAS (AP) — A guerrilla art collective claimed credit Thursday for changing a freeway-side billboard inviting Las Vegas tourists to fire high-powered assault-style rifles to read, “Shoot A School Kid Only $29.”
The altered advertisement, which had said “Shoot a .50 caliber only $29,” was taken down within hours and police began an investigation after the vandalism was reported, Officer Larry Hadfield said.
An email statement from the activist group INDECLINE took credit for the protest.
