Briefing Recall: Reconciling a BOLO with Two Callers
At 21:40 the briefing sergeant reads a BOLO and two callers' accounts. You will be on the street in four minutes and cannot take notes with you.
BOLO: dark blue four-door sedan, model years 2011–2014, dent in the passenger-side rear door, partial plate beginning "8G" and ending "42," driver a male in his thirties wearing a gray hooded sweatshirt with a red logo on the left chest, tattoo on the back of his right hand.
Caller 1 (21:15): "A dark car turned north onto Pine from Eighth. The driver had a gray hoodie. I think the plate ended in 24."
Caller 2 (21:22): "A silver sedan, four-door, went north on Pine. Didn't see the driver. Out-of-state plate, I didn't catch the numbers."
Dispatch notes that Pine is one-way northbound and that the streetlights on the 800 block of Pine have been out for three weeks.
1. Which details in the two calls conflict with the BOLO, and which conflict is most likely a recall error rather than a different vehicle? Explain your reasoning.
Read the worked answer
There are three conflicts: the plate ending (24 versus 42), the color (silver versus dark blue), and the plate origin (out-of-state, which may or may not match the BOLO).
The plate discrepancy is almost certainly a transposition. "42" and "24" contain the same two digits in reversed order, which is the single most common recall error for short number strings. Caller 1 also qualified the detail with "I think," a signal of low confidence. Treat the pair as one identifier with two possible orders, not two separate vehicles.
The color conflict is weaker evidence of a different car than it looks. The 800 block of Pine has been unlit for three weeks, so both callers were judging color under headlights and passing traffic. Silver and dark blue separate poorly in that light. Two independent callers agreeing on "four-door sedan, north on Pine" within seven minutes is stronger corroboration than the color disagreement is a contradiction.
What would change the analysis: a caller reporting a two-door, or a direction other than north on a one-way northbound street.
2. You have one radio transmission and four minutes. Which two identifiers do you broadcast first, and which BOLO details do you deliberately leave out? Justify the choices.
Read the worked answer
Broadcast first: the partial plate ("8G, last two digits 42 or 24 - possibly transposed") and the passenger-side rear-door dent.
Why these two: both are fixed, verifiable features that an officer can check from a distance without contacting the vehicle. A plate fragment plus a body dent narrows a very common vehicle profile - dark blue four-door sedans from a four-year span are everywhere - down to something an officer can confirm in a split second. The transposition caveat costs three words and prevents an officer from clearing a matching car because the digits read "24."
Leave out: the tattoo, the red chest logo, and the model-year range. The tattoo is invisible until contact, which is the moment you least need the description. The logo cannot be read at night through glass. The year range is unfalsifiable at a glance and consumes airtime that a second unit could use for a location.
A useful rule: broadcast what can be seen at distance; save what can only be seen at contact for the stop itself.
3. Caller 2 mentioned an out-of-state plate. How should that detail change the way units use the partial plate, and what is the risk of relying on it?
Read the worked answer
It should reduce reliance on the plate as a filter rather than change the broadcast. If the plate is out-of-state, its format differs from local plates, so an officer scanning for a local pattern may pass the right car - and the "8G" fragment may come from a different position in the string than the officer assumes. The practical adjustment: tell units to check the rear-door dent first and the plate second, and to read the entire plate rather than pattern-matching against a local layout.
The risk is treating one caller's impression as a fact. Caller 2 could not read the numbers and identified the color as silver, which conflicts with the BOLO, so the out-of-state claim carries the same uncertainty as the color claim. If dispatch broadcasts "out-of-state plate" as established, units may discount a locally plated car that otherwise matches the dent and the fragment - the two details that are actually reliable. The detail is worth a qualifier, not a headline.
