Not sure if this is a stupid idea but here I go. Some police forces own some drone units which are often dispatched to missing persons they can also be dispatched to major fires for a aerial view and possibly man hunts . This could be a expansion to large police stations costing about 100k which could cause missions to pay more and it may be interchangeable with the police helicopter on some missions. Around 65% of police forces uses it, it wouldn't be a requirement but a nice thing to have and makes missions pay more
Apologies if it is a stupid idea.
