Not at all but expensive manpower and equipment needs to be used with common sense.
Scanning through the various police helicopter units tweets that does not appear to be the case and frequently the helicopter crew are called in simply because they are there.
Just look at this disproportionate response to an incident that could have been sorted out on the ground by some old fashioned style policing.
This event was reported in Sidcups local paper last week.
'7 police cars and vans and a helicopter' called to Sidcup station after man prevents train from leaving.
Police were called to Sidcup station yesterday evening (January 15) after a man prevented a train from leaving by obstructing the doors.
At the time of the incident, which happened at around 10pm, Abbie Thomson tweeted: "Just followed a police chase, about 7 police cars and vans and a helicopter at Sidcup station.
"What the f*** has happened."
A police spokesman said: "We were called to Sidcup railway station just after 10pm after a report of a man preventing a train from leaving by obstructing the doors.
"BTP officers attended, alongside colleagues from the Metropolitan Police Service, and stopped two men close to the station.
"Words of advice were given and no further action was taken.
"The train departed prior to officers arriving."
Whoever authorised the response needs their head checking.
It was obviously a guy trying to hold the train for his late running friend.
It is impossible to enjoy London anymore without the incessant wailing of police sirens and the persistent sound of helicopters overhead. The city has more cameras than anywhere else on the planet.
In Singapore or Bangkok the matter would have been dealt with without the above scenario.
