[Sort of OT] Laser Beam To Discourage Thieves

[heather james]

power green lasers that were
3 to  7 times the power of the regular laser pointer "toys" ... and
warned that they had the potential of eye damage.
Can't you just see some ambulance chaser coming after you because
their client suffered eye damage by staring at your building alarm for
too long ...
