Context: Malone is bribing Michaels, a prosecutor, to drop a charge for illegal firearms possession. They meet in the Criminal Courts Building and Malone hands Michael a newspaper in which an envelope with money is hidden. Then they make a show for anybody who can see or hear them.

“You want this money or you don’t?” Malone asks. “But it’s for
a pass, not a plea.”
Michaels puts the paper in his canvas bag. Then he starts the
show. “Goddamn it, Malone, this gets tossed on a Dunaway.”
Probable cause.
A couple of people glance over as they pass by. Malone glances
over to make sure they’re watching and then for their benefit he
yells, “Known felon, and I saw a gun bulge!”
“What kind of coat was Bailey wearing?”
“The hell am I, Ralph Lauren?” Malone says, playing it out.
“A down coat,” Michaels says. “A North Face down coat. You
gonna stand there and tell me—no,
you gonna tell a judge—you
could see a .25 under that? I’m supposed to go in there and look like
an asshole? A racist asshole, to boot?”
“You’re supposed to go in there and do your job!”
“You do yours!” Michaels yells. “Make a goddamn bust I can
work with.”

My problem is with 'this gets tossed on a Dunaway.' I'm familiar with the vulgar meaning of 'toss' and I've found this: http://www.urbandictionary.com/define.php?term=Dunaway
still the phrase doesn't make any sense to me.
