Just out of curiosity ; If a police officer pulls you for speeding and doesn't have the speed equipment installed in his/her car for proof of evidence i.e dog unit; do they have the right to take your dash-cam away from you and use that as proof?.
What did you do?
Just don't have a dashcam with a built-in GPS.
Would they not need a warrant to collect evidence. A warrant that has to get there before the delete button get pressed or the SD card gets swapped
The images you capture on your in car camera are yours, and as such the choice of whether the police see them is also yours. Unless you hand them over willingly they must get a court order to make you do so, and the images are not likely to be retained on your SD card for that long!
