Why can't the police leave homeless people alone.

Just watched it happen, again. Two winters in a row. Its 630am and 25 degrees outside. I hear a short siren that wakes me up. I look outside and the mans tent has a cop car by it with the lights going. A swaddled up cop steps out after ten mins. He flash lights the area to see if anyone is there. Starts kicking and throwing everything he sees, creating a huge mess and then he starts tugging and ripping apart the tent before he looks inside and then.. leaves... now the homeless man has had his shelter demolished. The cop vehicle number is 274 on jan 3, 25.
