Pmac : Most likely right but if planed right and only between the boss and the killer it's possible .

The guys don't want to do the work and have everything set with stolen cars untraceable weapons etc .

The guys today want to use there own car and go get gas before the hit then go to the hardware store and get the tools they need and pay with a credit card !!!

I mean come on ! It may take a year on a guy to get his pattern and know where the cameras are and where they're not where they could be and where they couldn't be .

But still very much possible, just not likely in this get it done in 24 hrs. world we live in today.
