Installing security cameras would cost the complex $$$ and no way to recoup the expense. Make the tenants provide the DNA sample and they make money on you when they match your dog's turds.
They recoup their surveillance camera investment when they catch the perp not picking up the dog poop. At $500 a pop it wouldn't take long.
It would also keep tenants from submitting random dog poop that they picked up at the park to keep from being identified. You gotta think like a thief....a dog poop thief!!
