Three men scurried from the warden`s office, like cockroaches fleeing from light. Only Warden Jackson remained, eying the piles of consent forms they'd left behind. He smacked his hands together and licked his thin white lips. He mulled over what color jet he would buy, now that he was rich.
He called his guards up. "Twenty bucks a pop boys, that's my deal. However you get 'em is on you. All I care about is a legible name on the dotted line." Shit, he thought, rich as I am right now, I could afford to give 'em a hundred a pop, But I got better things to do with this petty cash.
Five minutes later, a red-headed guard from Mobile, Alabama huffed his way into the holding cell of Jason Mahar. "Get up!" he growled. "Read this shit and sign it!" He pushed the consent form toward the bed where Jason sat.
Jason rose from the bed. He accepted the form, scanned it, and dropped it to the bedside: "No sir."
The guard swung back his cattle prod and slammed it against Jason's face, knocking some teeth out and tearing a gash across his jaw: "God dammit boy, sign that mothafucka so I can get on to the rest of ya'll."
Jason resisted the urge to charge at this farm-boy-turned-city-overseer. "Not today I won't. Not me." The words slurred together as blood streamed down his chin. He sopped it up with his shirt sleeve, staining a black-printed ID number he had never bothered to look at.
ok, well, as you now know this isn't a hook. It's a first page. Do I want to read more? No. Corrupt law enforcement, brutal guards, senseless violence...well, normally of course that's a real plus, but it's almost Christmas. Peace on earth yanno.
The thing here is that it's senseless. You need to show the guards are afraid of the warden; afraid enough to beat the crap out of someone OR that they just like doing it. Better word choices can convey character without a lot of description.
And you've got some vocabulary problems. Holding cells are in jails and police stations. Prisons generally don't hold people temporarily and a warden is only at a prison, not a jail or a police statation. It's amazing what a life of crime (fiction) can teach you!
