When repeating information, often over the radio, police officers use what is known as The Police Letters Alphabet or the Phonetic alphabet. This form of alphabet is also used by other professional communicators such as military personnel, members of the armed forces and emergency personnel. The police letters alphabet is used when spelling out words, abbreviations or initials as to ensure that the correct information is passed along. Although there are different variations of the police letters alphabet, the most commonly known and used is: A-Alpha B-Bravo C-Charlie D-Delta E-Echo F-Foxtrot G-Golf H-Hotel I-India J-Juliet K-Kilo L-Lima M-Mike N-November O-Oscar P-Papa Q-Quebec R-Romeo S-Sierra T-Tango you-Uniform V-Victor W-Whiskey X-X-ray Y-Yankee Z-Zulu Professional communicators have been using phonetic alphabets since 1927 when it was first adopted by the International Telecommunication Union.
At my department it is different than in the military. It is used to keep there from being any confusion in relaying information to radio communications.

Please keep in mind that every police department chooses and governs how it communicates over its own radio system. This may be beginning to change somewhat, with the federal government trying to forward the notion of "interoperability" between departments, but as a practical matter the department, i.e. The chief of police, really determines what shorthand, codes, signals, ten codes, et al. Mean what on their own radio system. So to answer the question, the first thing you must do is determine which specific police department you want an answer for. I hope this helps.
They use the same alphabet the military uses. Why? Because speaking into their radio might muff up a transmission. Say the license plate you want checked is 147-NPO, the letter N might sound like the Letter M, so you say a word that starts with N like "November." the letter P could sound like G or D or B or E or C or V or T, so you say "Papa" because it starts with P. And you say "Oscar" for O.
Transmission would sound like this: "Plate Check for Wun Fower Seven November Papa Oscar." in turn the dispatcher would understand easier.

Unlike the ignorant answer above, the police, fire, and ems services have a phonetic alphabet, just like the military has their own version of the alphabet.

Most police officers have had previous military duty and already know both versions along with the 100 various 10 codes and 50 signal codes, as do firefighters. Police also have to learn and remember all of the traffic laws, civil and domestic laws, as they are ever changing.You should have a little more respect for the people that try their best to keep you safe.
So your are saying that the police have their own alphabet? I don't think they do. Most police aren't smart enough to learn the one that we all have let alone earn a new one.
