Memphis police tactical unit break into home, shoot and kill 67 year old suspected animal hoarder

So, the Memphis police SWAT unit breaks into an elderly man's home because animal control suspected him of hoarding.  They shoot him and "rescue" 28 well-fed, healthy animals (including chickens and a rooster, who were living outside).

Is it written somewhere how many animals you're allowed to have before the SWAT unit shows up?

Reason:

Yet another terrible tale of militarized police tactics gone wrong as armed agents do a forced raid on a Memphis man and shoot and kill him -- on a search warrant for being a suspected animal hoarder (and, of course, for according to the police raising a gun when the mini army smashed into his home).

From the Memphis police department’s website, on the Special Ops page:

Tact Unit

This elite unit, specially trained to respond to various emergency situations, is responsible for handling barricade situations, hostage rescues, counter terrorism, and high risk felony apprehensions.

And apparently, serving search warrants to suspected animal hoarders upon request of Memphis Animal Services.

And here:

Donald Moore lived in the home with at least 28 pets including cats, dogs, rabbits, hens and a rooster. "They were all well fed. He wasn't neglecting them like that. I think it was a hoarding situation that got out of hand," said Phillips.
