Killer thief

Sudden knife attack and your world stops,
on the corner outside the shop.
Hooded man stabs and goes for wallet.
His victim faints and embraces the pavement.
Shocked witness runs off, trips up and breaks his ankle.
The killer thief got both their money in the tangle.
Inside the bar came the killer thief.
Pulling a gun on a young couple.
And to their complete disbelief...
Handing the money over.
It seems he can strike when you least expect.
A bullet in the barrel or a knife to the neck!
