Jay,
I was very supportive of you and your concerns in the T C-T thread, and generally accepted much if not most of what you said.
Your inability to show proper research and understanding of police aviation in general, and in the UK before and after NPAS introduction makes me seriously reconsider your contributions to the T C-T thread and certainly to this thread.
Since when does a crime become such as to meet your criteria of 'cost effective'?
When the misper is your relative?
When the aggravated burg is on your property and has threatened you with a firearm? (He/she may still have the weapon while being pursued and willing to use it on following unarmed constables. The helicopter is ideal for this sort of pursuit.)
When the moped causes a crash that seriously injures one of your close family?
As previously stated, you really need to show a background of proper research: quoting random 'Tweets' does not even come close.
