Excesses are exceptions to the general rules in obtaining a warrant under Fourth Amendment searches and seizures. Exigent circumstances arise when a law enforcement officer has probable cause. Police officers in Lexington, Kentucky, had probable cause at the time, having conducted a drug bust; the police officer smelled marijuana coming from one of the apartments in the apartment complex. The officers did not have enough time to obtain a warrant without compromising the mission. However, officers entered the wrong apartment and placed three individual suspects in custody accused of crimes unrelated to drug trafficking.
