I too agree that it should bring jail time, but as you said LAW ENFORCEMENT AGENCY, HSUS and PETA are not law enforcement agencies the are boarderline radical groups pushing an agenda, they don't care about bringing one person to justice they care more about pushing animal bans across the board.
This. HSUS and PETA are no more "law-enforcement" than the NRA is.
IP addresses, email addresses, telephone numbers on caller ID, etc. are all easily spoofed.
