The FBI debated establishing an alert system seven years ago to determine who is making multiple gun purchases.

But the Wall Street Journal reports that the FBI abandoned the idea over legal concerns.

Such an alert system would have tipped off the FBI when the Orlando nightclub shooter made several gun purchases.

Mass shooters often make multiple gun purchases before carrying out a massacre.

The FBI and Justice Department are also considering an alert system to warn investigators when people who were once investigated for terrorism buy firearms.
