Without getting into debate - just keep an eye open for odd behaviour when in western style places, bars, or other areas these people might attack.
They tend to manage a few before the cops shoot them dead.

Jakarta. Indonesian police have blamed Islamist radicals for a low-powered explosive that detonated in the toilet of a mall on the outskirts of Jakarta on Thursday that mirrored a blast at another mall in February.
CCTV footage showed a man walking into the toilet at the ground floor of the Alam Sutera mall, on the western outskirts of the capital, carrying a bag and exiting shortly before the blast occurred.
“We've got the CCTV [recording] and also an idea [of who the suspect might be],” Insp. Gen. Tito Karnavian, the chief of the Jakarta Police, told reporters on Saturday. “But we can't disclose any more information pending the investigation.”
Tito, who previously headed the police's elite counterterrorism unit, Densus 88, said it was likely that radicals linked to the Islamic State were behind the blast, in which no one was injured.
