2nd degree criminal trespassing and assault from off duty officer while really intoxicated.?

the first thing is to file a police report which you still can and don't let them tell you you can't, then you need to positively identify the cop who ruffed you up and you have to be accurate, you then need the hospital report about your injuries and try to return to the house you mistook as yours and ask if they remember you, and last you need to talk to a lawyer but first get theses things because a lawyer will need them, you can also talk to the DA office and explain what happened, they may help you, being drunk and mistaking a house as yours is not a crime
