I posted a while ago about watching the mounted police practising in front of the old Town Hall in Vilnius.
Going through some old memory cards I found this video clip of the same event but in this one we were being watched by a police drone.
First there was a humming/buzzing sound then it suddenly shot out from behind the buildings alongside the square. As it hovered I got a better shot and you can clearly see the police markings. Then we spotted the operator working from a van near the Town Hall steps.
Were they getting a birds-eye view to improve their choreography? were they practising crowd surveillance? Or were they just playing with their new toy? Who knows?
