my son failed to appear at his sentencing court date. a warrant was issued. a few nites ago the police showed up at the door. i didnt answer. the deputy came around to the back door banging on glass sliding door with flashlite. the dogs ran over and opened the curtains and the deputy saw me. i quickly went over and closed the curtains and told him that i had nothing to say to him and to please leave. he requested i open the door and talk to him. i told him that i have nothing to say to you and they were to please leave immediately. they proceeded to leave the property and sit on the road for about 15 minutes and then left. do they have the right to go around my house looking in and knocking on windows just because i dont answer the door. what can i be charged with if my son is here.
