What you have to do, is, make a ruler with YOUR definition of how long an inch is.
The latest info on the slashing/stabbing with the knife, is, one white male who ran from building to building, slashing people on the head, face, and neck. The number I hear now is 15 with three not wanting treatment. The rest were sent to two hospitals. Critical and serious sent to a trauma Houston hospital by helicopter. Two are in critical condition, the rest in fair condition.
He ran and slashed/stabbed as he went so people didn't realize anything was happening at the other end of the hall until they got slashed as he ran by. Then ran in another building and continued to stab and slash down that hall.
If there had been a gun shot, people would have reacted quickly to get out of the way.
I would bet you there will be a call for a ban on knives and inches may be limited, Kart, so make your new ruler.
A day of reckoning is coming and coming fast!
