FWIW, the title is ambiguous, in that it could be referring to confiscation of illegal bikes, or illegal confiscation of bikes.MesquiteTim said:And finally, change the title of this thread. Your case is not about illegal confiscation!
A hyphen between the first two words would clarify it to the former, whereas a hyphen between the second and third would clarify it to the latter.
As far as "legal" or "illegal" goes, if something being done harms no one, in any way, I'm not sure there's a reason to worry about it.
If harm was being caused by hooliganism, etc., that would be another story.
