we have lost of clubbers here in theUK.
aside from perps using more firearms, secure in the knowledge that their victims will almost surely be unarmed, the 'cool' thing to use as a weapon is furry and four legged.
of course one should never bring a dog to a hyena fight.
and never bring a hyena to a lion fight
and never bring a lion to a liger fight,
and so on, ad nauseum.
the weapon is not important, it's the mind behind it's control that is dangerous, not the tool - well, maybe the t-rex...
