A prosecutor is handed a complaint charging harassment and a harrowed woman follows him into his office. The charges stem from an ex-boyfriend repeatedly making threatening calls to her over a recent weekend. She saved a voicemail where her ex-boyfriend said he expected to see her at a funeral. She then explains that two weeks earlier, he showed up at her door uninvited, called her names, and threatened her life before leaving when she threatened to call the police. On more than a dozen other instances over the past six months, she says he followed her by car, called and hung up, or waited outside her house. She can't give exact dates, and adds that when they were dating a year earlier, her ex-boyfriend hit her but she never reported it.
The prosecutor knows that the defendant is entitled to a jury trial on the harassment charge, reducing that charge is not an option, and it is a weak case. Having spoken with defense counsel, he knows that the defendant is not interested in taking any plea that would involve an order of protection for the complainant, and that he can't rightly plead the case without securing an order of protection. The case needs to go to trial, and yet it will require a Herculean feat to convince a jury to convict a man of harassment on the sole basis of a few phone calls and an ambiguous voicemail.
In order to convict the defendant, the prosecutor will need to show the jury evidence of the defendant's prior uncharged conduct towards the complainant to explain their relationship and the hostility of the phone calls. The People will be unable to prove the defendant's intent to terrorize without evidence of his prior phone calls and conduct towards the complainant. The complainant's memory is unclear, however, and she does not provide specific details or dates for the defendant's prior conduct. The prosecutor informs the complainant of the prospects at trial. He knows that the credibility, detail and likelihood of the prior conduct will determine whether the prior bad acts evidence will be admitted in his jurisdiction. (1) Whether the prior bad acts are clear and particularized may therefore decide the case before it is even begun. …
