"when you buy a replacement battery for a scooter, you often get the battery and acid in separate containers, and have to mix them."
Seriously? when did you last have one? the 50s? I have never heard of that.
"It's not as if someone who is going to attack another person with acid is going to balk at the idea of nicking a battery out of a car."
Its a lot harder though isnt it? how many batteries would you need? They'd probly just go back to knifing people.
I agree its a knee jerk reaction , but they already do it with glue and various other household stuff. Dosent seem to have handicapped kids significantly.
