Firstly, to those that doubt tasers are good, I am quite sure the guard and any family members are happy he was tasered and not SHOT. Those of you in the UK just don't seem to understand that in the US, that is the frequent alternative. With handguns available cheaply and easily on the streets to any 14 year old, I am rather glad to see that these perps at least bothered to avoid serious jail time if caught and spring for the less-lethal tasers. I'll bet the guard is too.

LESSON #1: PUT YOUR CO-LO IN A SAFE AREA. Deserted downtown city centers? Bad neighborhoods? Hmmm, maybe not...

LESSON #2: WTF have only 1 guard who has to leave the freaking secure room to use the toilet??? DUH!

LESSON #3: Underground is a great place for a co-lo...XYZ Airlines (a major US airline who I will not piss off by naming) has theirs under their main headquarters car park, under several feet of re-inforced concrete to stop truck bombs. With one secure freight elevator that is totally non-descript and VERY sucure, and walkway entrances that are difficult to remove equipment by..oh, and 3-4 staff in the secure ops room all day and night. They are not armed, but I am fairly sure the glass cage is bulletproofed...

LESSON #4: After three previous break-ins, realize that there is probably an insider giving away information...
