Stop & Question By Default

Even Before Reid's craptastic Stop & Question powers the Met have shown they are already using existing anti-terrorism searches to their extreme:

Police are using Draconian anti-terror stop and search powers for day-to-day duties. The powers, supposed to be kept for extreme circumstances only, have quietly been introduced into Scotland Yard's "safer neighbourhoods" programme which targets anti-social behaviour.
The widespread use of anti-terror powers was revealed in papers for a Metropolitan Police Authority meeting.
At present, under Section 44 of the Terrorism Act 2000, officers have the power to stop and search members of the public or vehicles, even if they have no grounds for suspicion.
However, suspects must be walking or driving in an area designated as being at risk of a terrorist attack.
But the MPA report says Section 44 is being used more widely in the "Safer Neighbourhood programme", which targets antisocial behaviour, criminal damage and graffiti.
Gareth Crossman, policy director of civil rights group Liberty, said: "They are admitting using exceptional powers, which the legislation says are specifically for terroristrelated activity. It flies in the face of the legislation."

London has been for a while a de-facto stop & question zone:

In February London police came under fire from their watchdog, the Metropolitan Police Authority, in a major report into the effect of counter-terrorism policing on the capital. The watchdog found that the force's use of special anti-terror stop and search powers were doing "untold harm" to communities in the capital, in particularly Muslims.

Under Section 44 of the Terrorism Act 2000, police officers may randomly stop someone without reasonable suspicion, providing the area has been designated a likely target for an attack. The power is currently in force across the whole of London.

Here is a handy cut out and keep guide to Section 44 of the Terrorism Act 2000-

DURING SECTION 44 SEARCHES

The police can only give you a pat down, remove outer clothes (eg - jacket, hat) search your bags, and have you empty your pockets

You do not have to give your name or address

You do not have to explain why you are there

You are not allowed to flee the search, but you are not required to be actively compliant. You are allowed to "go limp" as passive resistance during the search if you do not wish to comply.

There is no permission to collect DNA data during the search

You do not have to comply with any attempt to photograph or record you.

Women can not be touched by male police during these searches.

Make notes about the officers searching you - name, number, and police force.

Note the time and the events preceding the search.

Note the specific wording used by the police to explain their authority to search you.

Ask police for the reason that they are searching you. Specifically, are they searching for terrorists or are they simply trying to deter, delay, or inconvenience you?
