Porkies aren't protected, though, and there's no need to take a closer look before shooting.
Depeneds on where you live.

http://www.gf.state.az.us/i_e/pubs/ArizonaPorcupines.shtmlThis persecution of porcupines continued through the 1950s and 1960s until 1972, when a wildlife manager in Flagstaff named Wayne Anderson recommended that the season be closed on what was no longer a problem animal. Almost no one objected, and the Arizona Game and Fish Commission agreed: Conditions had changed.
The porcupine was no longer a noxious animal and has remained a protected species in Arizona ever since.
