It was my first day on the job as a newly qualified police officer in Florida.

I’d pulled over a vehicle for a traffic infraction. The driver stepped out of the vehicle and took off running. I radioed for back-up and the dispatcher asked “which direction is the suspect running?” and I realised I had no idea. Northbound? Westbound?

I had a compass in my pocket for just such an occasion. Only then did I realise I had failed to watch the YouTube video ‘How to use a compass’.
