Generally speaking, yes, I support the police.
That have to keep law and order ... and pursue and detain violent, selfish criminals. They also have to deal extremely awkward people/situations.
In short, their job is very difficult on a regular basis.
The UK has a particular problem with policing, especially policing and local communities.
A couple of decades ago in 1993, there was a black guy called Stephen Lawrence who was killed by racist thugs. His killers were never properly brought to justice (or it took way too long to bring them to justice - sorry, can't remember), due to police incompetence, difficulty in producing the evidence, and possible and assumed racist bias.
The aftermath of this was The MacPherson Report (1999), which basically labelled the entire police force as 'institutionally racist.' This is total bullsh*t. There have always been a few bad apples in the police, certainly, but the whole Met police cannot be condemned as 'racist'. In fact, it's a form of bigotry to do such a thing.
The MacPherson Report has had considerable ramifications. Stop and Search (called 'stop and frisk' in the US) has largely been discontinued since 2010, on the grounds that it is somehow 'racist'. It has been kept for terrorist suspects only but discontinued for gangsters, drug dealers, etc.
Result: London's levels of violent crime and gun and knife incidences have increased.
