Unwarranted search and harrassment

Ok, where to start... first off i live in a crime ridden african american neighborhood (im caucasian). Im a full time student as is my girlfriend, i have a 2 and a half year old son, and we both have clean records. We are just trying to survive and keep to ourselves.

On march 17, 2013 my girlfriend and i took a quick shower as my 2 and a half year old son watched some morning cartoons. After getting out of the shower and entering the bedroom i heard pounding on my front door, which i figured was just a relative or something. As i begin to get dressed I hear voices inside my house, i assumed it was my girlfriends father. The voices began to not sound right so i peeked my head out of my bedroom and at the end of my hallway is a police officer saying PD come out of the room, "where is (ill refer to this person as swim) swim". (swim is a man i dont even know, he randomly comes to my door occasionally asking to bum a cigarette. Ive never let this person in and have no connection other than this.)Me and my girlfriend are both naked. So I put pants on and walk into the living room to see my son on the couch and 3 officers standing in my living room. As i look out the front door i see 2 possibly 3 patrol cars. I see out the back window and theres 3 cops parked right at my back gate, so my house in surrounded my patrol cars. Officer number one starts walking down the hall and officer number two says an officer saw swim at my house a couple days prior and asked where he was. (He stopped by asking for a cigarette, i said no and went back inside). Than i hear my girlfriend say you cant just walk in here your breaking the law. Officer number one than says, well looks like this is gonna turn into a matter of welfare. And officer number two says the door swung open. At this point officer number three walks outside the house. I say the front door was closed, you were pounding on it, it didnt swing open. Than officer number two says your son opened the door. (My son cant open my front door, hes not tall or strong enough) Officer number one searches my bedrooms and than comes back out and officer number two asks for my name and age. While officer one was searching officer two is repeatedly telling my son "you opened the door, you opened the door". They let my dog out and she took off running around the neighborhood annoying and irritating neighbors. My son is in shock at this point and all day he kept staring off blank saying i opened the door, but i didnt daddy. The police came to my home expecting to be confronted by african americans, the police in this town are also known for racism and unfair treatment towards blacks. My girlfriend and i both have been going through what feels like shock, we cant think straight, cant sleep, and poor memory. I feel violated and unsecure. All my neighbors now look at me like im up to something on their "turf". I feel like im being watched everywhere i go and like im some sort of criminal. Does this sound like something i can try filing a tort for? My civil rights have been violated and i feel like ive fallen under their typical stereotypical regime. Any advice would be appreciated
