The vast majority of homeowners with fire insurance never file a claim but we don't say fire insurance is a bad idea. Having the insurance *is* using the system. And I think that people actually understand this *because everyone needs health insurance*

This isn't a time for the FBI to quietly urge anything. They should be yelling it from the rooftops.
New: The FBI is quietly urging ICE agents to properly ID themselves in the field.
In a bulletin to law enforcement last month, it warned of criminals posing as ICE to rob, rape, kidnap—a problem it says now demands national coordination to confront.
