    no, they only use that as a backup. they actually use doppler shif to accurately measure your speed. the reflected radar pulse will be frequency-shifted towards the red end and the amount it is shifted by is proportional to how fast you are going, and it is this shift that the cameras actually detect. the camera then takes 2 photos a small interval apart, and then in court to back up the primary (ie doppler shift) reading they use s=d/t from the photos to prove it.

    Whats the best way to destroy a Gatso?

    I heard that soaking a tyre in petrol, chucking it over the top and then lighting it works well .
