” The New York Post and the head of a New York City police union are upset that an accused drug dealer with a prior record may walk due to “a technicality.”

Judge Jack Weinstein voided evidence against Shakeel “Blam” Wiggins last week because an NYPD cop didn’t properly fill out a search-warrant application that turned up the weapon as well as a handgun and a cocaine cache last September, court papers say.

The ruling will likely allow Wiggins, a prior felon, to walk . . .

“ New York City police officers put their lives on the line to get these illegal weapons off the street,” Patrolmen’s Benevolent Association boss Patrick Lynch said of the ruling. “There are some technicalities — like if the premise is a single- or multiple-family dwelling — that are so insignificant that suppressing the evidence actually subverts justice and public safety.”
