Interesting take, considering the Tokarev is renowned for it's ruggedness (it could withstand tremendous abuse), reliability, simplicity, power and accuracy. Hell, even the Wermacht was issuing captured Tokarevs to their own units. In fact variants of the Tokarev are still in use by various security forces today. Not to mention they are very popular with target shooters in the West.
I'm also willing to bet most tankers regarded a sidearm as worthless. In regard to the Russians, if the Germans can take out your mobile, decently armoured, 30-35 ton 76mm gun platform, what are you gonna do to them with a little pop gun?
I'm also aware that Stanley didn't declare self-defence as his defence, but I'm also not buying his accidental discharge story either. The only reason I mentioned self-defence is that it is supposed to be the only justifiable reason for blowing somebody's brains out.
Don't get me wrong, if these kids weren't busy being little criminal shits, Boushie would probably still be alive today.
