"...unless the offenders are Muslim, in which case, because it's their heritage to do so, no crime has been committed."
Since Muhammad, the perfect Muslim man, had sex with Aisha when she was 9 years old , a 12 year old is fair game.
To imply otherwise is an affront to Islam.
If these girls were in burkas that is a different story, but if they weren't, and were scantily clothed by Muslim standards it would be OK.
Muslims should abide by Allahs laws(Sharia) as exemplified by Muhammad, and not by our man made Kafir laws. -Tom
