Don't be ridiculous. If she had sex with multiple partners before OR after being with Bryant, there is no way on earth a prosecutor could prove Bryant was the one who caused those "jaw dropping" injuries.
This DA is NEVER, EVER going to be able to prove FORCE, period.
Perhaps, perhaps not. But I'm talking about the act itself, you're talking about the ability to prove the act, which are two different things. The inability to prove he did it results in a "Not guilty" verdict, but it doesn't mean he's innocent. Ask OJ.
