Sicario - Ultimo incarico

The coded note The Virtuoso receives at the start of the film reads:

"Once there was a worn and withered old man too set in his ways, bound by routine to have the fore-sight to understand that in all his seventy-six years he's always done the same thing, ate the same food, chose the same colors, won the same battles. His life a breathing pentagon: home, work, rest, eat, dream. From age eighteen he'd never questioned his lot. Until, the trinity... and the agony of realization that a life lived can never be re-lived."

The Virtuoso spends a large part of the movie explaining his meticulous nature, and spends most of the movie being incredibly cautious. However, when tending to Johnnie's girlfriend, he opens the cap to a peroxide bottle with his mouth, leaving DNA everywhere. He then moves and plugs the space heater in with his bare hands, leaving his prints everywhere, all while holding his gloves instead of wearing them.

The cap of a peroxide bottle is hardly "everywhere" and why should he worry about DNA or prints. In rural, out-of-the-way towns, CSI teams don't turn out for burglaries gone bad.
