It could be soldiers, special forces, paid henchmen etc. Throwing the same question back to you, how come no one has surfaced, i.e. claiming they were involved in getting these weapons for the lal masjid to begin with? I mean things have a tailpipe dont they, if you think someone has to come up and claim they were planted, assuming thats not the case, then whoever supplied the masjid must surface and make a claim too.
Again, please dont resort to lying. They did have a few weapons, and despite the measures the Pak military took, they did put up a good fight, for a long time.
As if this is the first time the Govt planned such a thing.
For someone whose loyalty and allegiance to Musharraf has blinded him, I dont need to bother with that.
The only disaster was the Govt arming them, supporting them, funding them, appointing them, and then in the end going all out against them, killing many innocent people in the process.
Just like how there is a connection b/w the taliban and lal masjid 
Again, you dont need to lie ravage, unless you can prove I said they are using ghulails or otherwise just keep a lid on it, rather than mindlessly parroting the same lies over andover again. They had guns, as in AK47s we all know that, even they claimed they had 13 of those, which is more than enough needed to kill 8 or so soldiers that they took out. And if you think those are sophisticated hard to find weapons, you will find them all over your karachi or peshawar too, licensed and unlicensed so dont be shocked or expect a military aaaperation in those places based on that.
