From your article. The charge did not mention where they prayed is the little point presented? They do open their Friday services, how about all of them to the public.
“It is unclear what role, if any, religion played in the attack Mr. Shnewer and the five other men are charged with planning. (The sixth suspect, Agron Abdullahu, had no apparent connection with Al-Aqsa or the South Jersey Islamic Center.) The authorities have described the suspects as Islamic extremists, but the lengthy criminal complaint summarizing the F.B.I.’s 15-month undercover investigation of the group does not mention where — or how often — they prayed. Certainly there is no evidence that they picked up radical ideas at either mosque.”
