Good thing there were so many policemen there.
US police are searching the home of suspected gunmen who attacked a conference on cartoons of the Prophet Muhammad in Dallas, officials say.
An FBI official said agents were collecting evidence at an apartment in Phoenix, Arizona.
One suspect was identified as Elton Simpson, who had been previously investigated on suspicion of terrorism offences, US media reported.
Two gunmen were shot dead after opening fire outside the contest on Sunday.
They drove to the Muhammad Art Exhibit in the Dallas suburb of Garland as the event was ending, shooting at and wounding a security officer before being killed by police.
Sunday evening's event was organised by the American Freedom Defense Initiative (AFDI), which is run by controversial blogger and activist Pamela Geller.
One of the keynote speakers was the Dutch politician Geert Wilders, an outspoken critic of Islam in Western societies.
The conference included a contest that offered a $10,000 (£6,600) prize for a cartoon of the Prophet Muhammad. Depictions of the Prophet Muhammad are offensive to many Muslims.
