What's proper police protocol?

Prosecutors dropped all charges against Henry Louis Gates Jr. on Tuesday. The prominent Harvard professor had been charged with disorderly conduct after breaking into his own home in Cambridge, Mass. This bizarre episode, which some say is an example of racial profiling—Gates is African-American—raises all sorts of questions for the Explainer.

Gates repeatedly requested the arresting officer's name and badge number. Gates says the officer provided neither, although the officer claims that he did, in fact, state his name. Was the officer required to provide this information?

Yes. Massachusetts law requires police officers to carry identification cards and present them upon request. Officers are also required to wear a "badge, tag, or label" with their name and/or identifying number. The law is aimed at precisely the situation in question—suspects who feel their rights are being violated. Few other states impose this requirement on their officers as a matter of law, but many individual police departments, such as the New York Police Department, have adopted it  (PDF) as a matter of policy.

Gates initially refused to emerge from his home and provide identification. Was he required to?

No. There's nothing to stop an officer from requesting your presence on the front porch or asking you questions, but he cannot force you to identify yourself or come out of your house without probable cause. (The rules are different for drivers and immigrants, who are required to provide identification upon request.) If you don't feel like chatting, ask the officer whether you are free to go about your business.   (If he answers no, you are being detained, which means the officer must acknowledge and abide by your full menu of civil rights, including the famous Miranda warnings  if he intends to ask you any questions.) *

The arresting officer alleges that Gates shouted at him and threatened to speak to his "mama." He then arrested Gates for disorderly conduct. What, exactly, is disorderly conduct?

Behavior that might cause a riot. Massachusetts courts have limited the definition of disorderly conduct to: fighting or threatening, violent or tumultuous behavior, or creating a hazardous or physically offensive condition for no legitimate purpose other than to cause public annoyance or alarm. (The statute, however, just says "idle and disorderly persons," a formulation that is, on its own, patently unconstitutional.) Violators may be imprisoned for up to six months, fined a maximum of $200, or both.

The stilted language in the Gates police report is intended to mirror the courts' awkward phrasing, but the state could never make the charge stick. The law is aimed not at mere irascibility but rather at unruly behavior likely to set off wider unrest. Accordingly, the behavior must take place in public or on private property where people tend to gather. While the police allege that a crowd had formed outside Gates' property, it is rare to see a disorderly conduct conviction for behavior on the suspect's own front porch. In addition, political speech is excluded from the statute because of the First Amendment. Alleging racial bias, as Gates was doing, and protesting arrest both represent core political speech.

Correction, July 28, 2009: The original version stated that mere detention triggers the reading of Miranda warnings. In fact, custody paired with interrogation triggers the warnings. (Return  to corrected sentence.)
