Why is it that travellers who decide upon themselves to park in car parks are not given parking tickets?

If the answer is they move on and fines cannot be collected then on the spot fines should be given to them and their van should be towed to a compound.

If the police cannot do this get the army in who would certainly take control of the situation. You might think this is over the top but I'm sure a lot of people would agree with me as we are totally fed up with these people doing just as they wish and nobody having the guts to do anything about them.
