Probably would be smart, now, to send unidentified tracking devices to a friend in Madagascar, via boat, and then return it to the local police via whatever boat Greta Thunberg is riding... you know, to reduce CO2 impacts. That way, there is no 'mens rea', or mental intent, to deprive the officers of their property. On the stand, the alleged thief could truthfully say, "I sent it to the local police station, address XXX YYY St, etc. etc.".
