Its not a good first scanner, but it is a good first Wide-Coverage Receiver that has scanning capability.
They make exceptional receivers, that cover pretty much the entire spectrum of RF where most voice communications happen. All mode so you'll get USB, LSB, AM, FM, WFM. But if you're wanting a police scanner, you're better off picking something like the Radio Shack PRO-97 or Uniden BC-246T or BDC-396.
It sounds like for what you want to do you'd be better off with a trunktracking scanner like the ones I listed above.
