Why is it difficult to bite your own arm. I used to do it all the time in grade school. I thought the teeth imprints were cool. The key was biting hard enough to live imprints without making it hurt. Really a delicate science bordering on art.A lawyer's favorite question - were you lying then or are you lying now?
Was she lying when she telephoned the police (doubtful - given the police report referencing the physical injuries). It is difficult to bite yourself on the arm, etc.
Or she is lying now to protect a bad guy? Much more likely Maybe they worked out a deal for him to give her money in return for retracting the allegation before a criminal case was filed.
