Night Angel and SB44, if it were your car - be it a 10 year old Toyota or a brand new Range Rover, I'm sure you'd appreciate the attention of the Sheriff's Office in tracking down the do-er's.

Yes, resources are being used...but in the absence of the great bank robbery, murder, or mayhem, they're trying to do their job to protect the public from crime in progress. If something bigger were to present itself, I'm sure the resources would be diverted to that.
