A new development in local law enforcement has been reported by the Los Angeles Times. The police department has something called the Rumbler, which is intended to get people's attention. It is mentioned that if the siren is not audible, the Rumbler will still be felt.

This suggests that the Rumbler is a tactile warning system, but details are sparse. For more information about the Rumbler and its purpose, readers can refer to the Los Angeles Times for further details.
