Putting it kindly, this is an incredibly optimistic interpretation of how historically the government and police have used their powers. There is a long and consistent history of UK police abusing powers, stretching legal definitions and using technology to target those outside the original mandate of a law or investigation.
Antiterrorism and anti-disorder laws sold to the public as needed to prevent serious threats have been used extensively outside of what I think most would consider reasonable to surveil people, restrict freedoms and harass. The prime example are the stop and search laws, used to search a large numbers of people, predominantly based on racial stereotype, with zero impact on terrorism.
Remember that the Met police is known to be institutionally racist & sexist. It is not an organisation to be trusted.
