LAPD Shoots and Kills Dog As Owner Celebrates Knicks' NBA Championship

9:34 AM -- The Los Angeles Police Department has issued a news release on the shooting. They said in a statement ... "The officers met with the person reporting (PR) who directed the officers to the apartment unit. The officers contacted the resident in the apartment unit; while speaking with the resident, a large dog was by its side barking at the officers."

They continue ... "The officers asked her to secure the dog, and the resident closed her door momentarily. She re-opened the door, and the dog exited the apartment. Once outside of the apartment, the dog charged at one of the officers, resulting in an Officer-Involved Shooting (OIS)."

LAPD says the Los Angeles Department of Animal Services responded and took Jameson's body. They added Marie was cooperating with authorities.

According to the release, the Force Investigation Division is investigating the incident.

LAPD shot and killed a 2-year-old dog who wasn't doing anything wrong ... at least according to his owner.

Cops were responding to a call Saturday from a resident who wanted them to check on a screaming woman in a Canoga Park condo building. When officers arrived, they fatally shot the woman's dog, Jameson, claiming he rushed at the officers.

But his owner, Marie Marseille, says that's not what happened. She told FOX 11 ... "Jameson wasn't baring teeth. He wasn't growling. He wasn't aggressive. He wasn't barking. He was just moving towards the officer."

Video of the emotional aftermath shows Marie wailing over the dog's body as about 10 officers mill around.

At one point, a neighbor yelled at them ... "What is the purpose of all of you?" Another clapped and sarcastically said ... "Hey, good job. This is what we pay for. Amazing. Amazing. Good work, guys."

Moments before the cops allegedly killed her dog, Marie had taken a picture of him in a New York Knicks jersey.
