When your defense involves you testifying in your trial, the prosecution is almost certainly going to do something called “impeaching” you. Unlike in politics and government, where impeaching often means seeking to remove an official from office, impeaching in this sense means offering proof that casts doubt upon the truthfulness and reliability of the person testifying. Whether or not you’re testifying in your own defense at your criminal trial, one thing you definitely need is representation from a skilled and experienced Maryland criminal defense attorney.
There are lots of ways in which the prosecution can try to impeach you as a witness in your own defense. In some circumstances, the law may allow the prosecutor to bring up past criminal convictions you have on your record. One of the rules that the law imposes, however, on this type of impeachment is that the conviction’s significance and connection to the alleged crime(s) at hand must be greater than the potential that the information will unfairly bias the jury against you, the defendant. When you hear a TV lawyer or judge talking about evidence whose “risk of unfair prejudice outweighs its probative value,” that’s what they’re talking about.
Here’s a real-life recent case that gives a good example. B.H. was a man on trial for several serious crimes. A shootout in a parking lot in Baltimore left B.H. facing charges of attempted murder, assault, reckless endangerment, drug possession and several gun crimes. Part of B.H.’s defense was to argue that he did shoot a gun that night, but that he did so in self-defense.
