Over here, you find them, ring police, wait several hours if not days depending how busy they are, (in my case it was over a week) for them to give you a crime No' for your insurance company so you can make a claim.
Darren: "Hello, police? There a chap trying to break into my shed? Fancy popping over and nabbing him?
Police: Sorry old chum - bit busy at the mo. How does next tuesday sound?
Darren: Hmmm... not so good to be honest. Wait.... Ah... it's OK... I've just shot him myself... winged the blighter in the leg...No need to rush now. See you on Tuesday.
Within thirty minutes: 1x helicopter, 2x armed response units and 25x police officers.
Of course - you don't ACTAULLY shoot said ruffian - but a good way to get a rapid response.
This is a joke, but lacksidasical response to theft seems to be getting worse. After repeatedly loosing camera's and laptops during air travel- with zero botherment from the airlines - I now take a starters pistol with me on all plane journeys. You get to the ticket counter and state you have a starter pistol. You get given a big steel box with 2x locks. Put the pistol in the box, drop in camera/laptop etc ( although needs to not be a huge laptop ) and then everything solid and secure, and backed up with vast amounts of paperwork - when you land. Have done this maybe 12-14 times now, no issue, no "homeland security" problems or big questionings about why your carrying a starter pistol. Only adds about 5 minutes to the check-in process, and I can attest that the Indian, US and UK authourities are fine with this. Although YMMV with other countires.
Back on topic....
I have a Yale house alarm which is wireless and modular. I've added another sensor into the garage, and a second siren INSIDE the garage as well. After much swearing and reading of instructions, the siren in the garage only goes off if someone breaks into the garage. The siren is so deafening in the confines of a garage that within a minute or so it becomes difficult to function - I don't think you can cope with it long enough to practically steal anything.
A local garage ( Car mechanics to those in the US Of A ) does this, but also has 2x strobe lights which were previously used for stadium rock gigs - something ridiculous like 1500 watts. My friend was "volenteered" to test the system, and ran into the garage with the siren and the strobes. He found it so disorientating that within a minute he was having difficulty moving, and desribed the experience as feeling as though his limbs were disconnecting from his body. He left the garage on his hands and knees.
