Firstly, what you say is nothing but conjecture. Can you provide some evidence that only threats against muslims are followed up by the police, not when they're against white people? Or are you just going on what Lennon and his mates say?
I wouldn't be surprised if Stephen has had threats made against his family. He threatened the entire muslim population of the country with violence, the speech can be found on youtube
http://www.youtube.com/watch?v=yH575nwLIAU. Doesn't make it OK, I actually feel a bit sorry for the guy, he's way out of his depth, but it's hardly surprising. 5% of the population is bound to have some nutters among it. Normally, threatening a section of society with violence like that would get you in quite a bit of bother with the police. Not our Tommeh. He also broke his bail conditions numerous times. He can be seen on youtube appearing at an EDL demo dressed as a Rabbi when on bail, the conditions of which were that he not appear at EDL events. Normally, breaking bail conditions lands you in custody. Not our Tommeh. One might even think that there was a two-tier system in favour of him, given the
evidence.
