“Did the police get his computer’s IP address?” — How would they? That’s non sense.

Police would first have to identify WHAT IP ADDRESS is involved, Police can not find out about that IP address without first looking for it. And, once found, THEN they could trace it back to the subscriber using it.

How would they first find the IP address?

One solution would have been to monitor ALL Morocco traffic to Facebook until some one signed up as P_r_i_n_c_e M_o_u_l_a_y R_a_c_h_i_d.

But that would be MASSIVE wire tapping!

Another, even more invasive method, would be to have been RECORDING all traffic, all the time, and then simply searched the records… Requires quite a lot of storage capacity depending on retention period, but still feasible.

Either Facebook provided the info or else ALL Internet traffic in Morocco is easily readable by the authorities.

Or did I missed something?
