[EX Q]: No, the gun (+one set of ammo) still costs more than restocking pepper spray for a lifetime (calculation: pepper spray @~Σ7 per year, handgun @~Σ500 = ~71 years)
[EX A]: Valid

[EX Q]: I think the gun grabbers have deep seated emotional problems that need dealing with and should be denied their Second Amendment rights.
[EX A]: Valid

[EX Q]: However, given existing work on the adverse impact of other safety laws, such as safety caps for storing medicine, even the very plausible assumption of reduced accidental gun deaths cannot be taken for granted.
[EX A]:
Valid
