Your not a good risk planner I see,the risk vs reward in your master plan is insane,after fencing the jewelry you'll end up with about $5k & risk doing life in prison .
For that kinda risk you'd be better off going full blown psyco maniac & robbing a pharmacy that caters to pain management patients,start out by car jacking a senior citizen & breaking his hip ,then head directly to the pharmacy, as soon as you enter take out your pistol & fire a few rounds into the ceiling so they know you mean business, then pistol whip the living shit out of the counter girl to set the mood.
Next you'll want to force the pharmacist to give you some amil nitrate caps before you tie his ass up with the telephone wire ,snort a few of the poppers the pharmacist just gave you ,then shoot him in the ankle ,lock the customers in the basement after robbing them of all cash & pills, dont forget to fondel the hot girl on methadone before you throw her down the steps on her face & bolt the door, next you'll want to start a raging fire to destroy all evidence & leave no wittnesses, roll the obese woman in a Rascal scooter out into traffic to create a diversion after you take her script of amphetamines she just filled, then take the counter girl hostage & lock her ass up in the trunk, that way if the cops shoot at you as you flee she will stop the bullets, crash thru a few road blocks as you make your way across state lines with $500,000 worth of narcotics in a stolen car & your home free with half a million !
Are you taking notes here
If your desperate enough to do all that I'll personally front your ass a pound of primo,if only to save the obese woman in the scooter .
