Jackson v. U.S.: Being Nervous Does Not Mean You Are Dangerous

Jamison KoehlerCriminal Procedure, Opinions/Cases

And sometimes the D.C. Court of Appeals gets it right. A police officer sees a woman driving a van with what he believes are illegally tinted windows.  When he activates his lights for a traffic stop, the van pulls over immediately.  The van begins to “rock” with lots of “shaking,” and when the officer walks up to the driver’s side …

Henson v. US: Consensual Encounters and Unprovoked Flights under Henson v. U.S.

Jamison KoehlerCriminal Procedure, Legal Concepts/Principles, Opinions/Cases

One of the problems with bad law is that it leads to even worse law. I have never been a big fan of the U.S. Supreme Court’s decision in Illinois v. Wardlow, which held that being in a “high crime” area (what part of any U.S. city does not have a lot of crime?) and running away at the sight …

Interpreting “Joint Constructive Possession” in Tamara Smith v. U.S.

Jamison KoehlerCriminal Procedure, Legal Concepts/Principles, Opinions/Cases

If constructive possession is a legal fiction, then joint constructive possession is a double legal fiction. It is not only that you do not actually possess the article in question (and by actual possession, I mean physical occupancy or control over the property). It is that other people – it could be one person, it could be four other people …

Jefferson Memorial

On Getting Your Own Witness Locked Up

Jamison KoehlerAssault, Criminal Procedure, Professional Responsibility/Ethics, Trial Advocacy

  I put our star witness in jail. I have heard about prosecutors being slammed for doing this. One of my adjunct professors in law school – a prosecutor in Philadelphia – ended up on someone’s list of the top ten worst prosecutors in the country for having one of her witnesses in a murder case sit in custody for …

What is a “Testimonial Statement” under Crawford v. Washington?

Jamison KoehlerEvidence, Legal Concepts/Principles, Opinions/Cases

You know you are in trouble the moment the judge refers to “that Supreme Court case on confrontation.”  He adds: “Robinson I think it is called.” The judge is a highly respected senior judge.   Although you realize he doesn’t do many criminal cases, you are still somewhat taken aback by his comment. Robinson?  Are you kidding me? Standing there with …

Mason v. U.S.: When Is A Prior Consistent Statement Admissible?

Jamison KoehlerEvidence, Opinions/Cases

I love appellate cases on evidentiary issues – which the D.C. Court of Appeals seems to be doing a lot lately — because they allow me to take out my handy-dandy McCormick on Evidence guide. According to McCormick, there are three things you need to know about the credibility of a witness:  bolstering, impeachment, and rehabilitation. Impeachment and rehabilitation are straight-forward. …

Longus v. U.S.: On Bias, Extrinsic Evidence, and the Collateral Fact Rule

Jamison KoehlerEvidence, Legal Concepts/Principles, Opinions/Cases

Bias is “the powerful distorting effect on human testimony of the witness’s emotions or feelings towards the parties or the witness’ self-interest in the outcome of the case.”  That is McCormick on Evidence, and it is the clearest, most accurate definition I have ever seen of what constitutes bias. McCormick continues: “[B]ias, or any acts, relationships, or motives reasonably likely to produce …
