The police can seize anything as evidence yes, no they don't have to arrest you to do so
Not true. The police can only (legally) seize things when they have a power to do so (like in your bad example where there was a specific power to seize and dispose of alcohol)
they may need to get a warrant without an arrest to make a search of property
you may note you just said 'property'. Police dont get court warrants to search people in the street and to retain any items they find, they use other powers for that.
and they might search your property with one take items and then not arrest you
Yes but they have still used specific parts of the law to get the search warrant and to seize and retain any property they find.... for example under sections 8,19 and 20 of PACE 1984
and an arrest might mean they can search your property without a warrant.
Yes again under the law, typically either sections 32 or 18 of of PACE 1984 depending on whether the person was in/ just leaving the address when arrested or not.
Again carry on googling, just maybe read more of each section than the bits you want to cherry-picK
I dont need to 'google' because unlike you i actually have a reasonably good idea of the law, in England and Wales, around police searches, seizure and retention of property.
No, it was a perfect example of how to use pace and police effectively without HAVING to arrest people.
It was an example where the law provided a specific power of seizure and disposal outside of an arrest. Something you have now repeatedly failed to do in relation to your claim (simply because no such power exists and you were talking nonsence)
We all get it, you will turn a blind eye and make excuses as long the police abuse people you don't like
I have literally been outlining the legal ways in which police can carry out their job around arrest/ search/ seizure of items etc.
It was you that had suggested the police could act outside of the law and seize items where there was no legal power to do so!
just get off your high horse. Someone might have a rape alarm nearby and you might fall off.
High horse? I get it .... your have been caught out talking nonsence, your attempt and providing an 'example' spectacularly backfired and all you have been able to do since is repeat the same stupid, refuted talking points in an obvious attempt to refuse to either be quiet and skulk away or accept you were in fact wrong!
