Report of up to 20 people shot in San Bernardino

From Hotair:

No details yet beyond the number and the fact that, as best we know as of 2:30 ET, the shooter is still active. Stand by for updates.

Update: An ABC affiliate in SoCal says 1-3 shooters are being sought, but the possibility of multiple shooters is routinely mentioned early on after news like this breaks. In reality it’s almost always a single shooter.
