A Baltimore County cop shot a 14-year-old boy Monday night in what police are calling an “accidental” shooting.

But gun enthusiasts say there is no such thing as an accidental shooting, referring to an unintended shooting as a “negligent discharge,” a result of not following basic safety rules.

The boy is expected to survive.

The cop was off-duty, working security for an apartment complex where he was told to watch over a vacant building that was under construction and not let anybody inside.

However, the 14-year-old boy made it inside before he stepped out on the second-floor balcony.

That was when the officer fired his gun.

According to the “Baltimore Sun:

Police said two county officers working off-duty at the Woodridge apartment complex, in the 9600 block of Southall Road, were investigating reports of people inside a vacant apartment. One of the off-duty officers told police that when he saw someone come out on a balcony of the apartment, the officer “was pointing the weapon in the direction of the balcony” when “his weapon discharged accidentally,” the department said in a statement.

An NYPD cop who killed a man in what he called an “accidental discharge” was indicted today on manslaughter charges.
