According to Anne Arundel County police, Robert Knickerbocker was going through the restaurant's drive-thru in his Mercedes 300D when he began blowing the horn and cursing at Taco Bell employees.

"He was also on his phone there for a while in the drive-thru again, using expletives and not following directions of the employees in terms of pulling up," Anne Arundel County police spokesman Justin Mulcahy told WBAL. "Employees called the Police Department just feeling like police needed to respond to deal with this person. It's actually what started the investigation." Knickerbocker, who smelled strongly of alcohol and had glassy eyes, told police that he was a police officer for the Maryland Natural Resources Police. That claim proved to be false, although Knickerbocker is a volunteer reserve officer for the MNRP; or at least he was.
