That was one of the worse botched hit attempts ever!
Casso was sitting in his car eating an ice cream, I'm assuming they wanted a quick hit & run/ driveby but if your going to do it, at lease do it right
And they all paid massively for their screw up. If it wasn't right, then perhaps they should just have aborted it & regrouped
Their were seasoned guys in the car too so it's not like their first hit
