Look - the deer can’t pay city taxes.
It should not exist, therefore...
Now if it was an undocumented Mexican or Syrian deer, it would have enjoyed sanctuary city treatment.
I had a neighbor from India. He was a master gardener. His entire property was shrubs, small trees,vines, etc..... No grass whatsoever. Everything produced a fruit or edible thing. He kept a pygmy goat to keep everything trimmed up neatly at ground level to four feet up. The city fined him $110 per day until he got rid of the goat.
