I can tell you're a fucking copper
Are you going to answer the question or not? Which individuals and which groups are being targeted?
Correction- I used to be a copper but I'm alright now
I don't know what (if any) individuals or groups are being targetted at the moment.
To use stop and search effectively, you have to target the individuals or groups that the information/ intelligence suggest are responsible for the offences you are trying to combat.
The link you quoted above carries a lot of data but, this strand of the thread was instigated by a stabbing. The data in your link relating to knife crime was extrapolated from information from The Met-
In relation to knife crime, a 2018 report entitled ‘Justice Matters: Disproportionality’[footnote 11] references data collected by the Metropolitan Police Service. This work showed that in London in 2017, 50% of knife crime offenders were BAME (up from 44% in 2008). In this total, 50% were under the age of 25 and the majority (90%) were male. 50% of knife crime victims were BAME. A similar pattern emerged when examining knife crime with injury. In 2017, 83% of offenders were male, 35% were aged between 17 to 24, and 69% were BAME. Victims of knife injuries shared a similar profile with offenders. 78% of victims were male, 32% were aged between 17 to 24, and 55% were BAME. Ethnic disparities were also evidenced when looking at knife possession. In 2017, 53% of possession of knife suspects were Black, and 37% of all suspects were Black men under the age of 25. This resonates with the arrest data on stop and search which showed that 56% of all people arrested for offensive weapons following a stop and search were Black.The Met is a very different and totally fucked up organisation compared to Wiltshire Police or my old employer- Thames Valley Police. Extrapolating the stats for the whole of England and Wales on figures from The Met is like basing information about Swindon Town FC's performance against figures produced by Manchester City FC- not singing from the same song sheet. Granted as I said before, every force has officers whose motives are suspect. Once identified, these officers should be dismissed and barred form policing for life.
So, to further answer your question about who is being targetted- if the intelligence and information for Swindon suggests that a particular crime category is being commited by a particular section of the community, be they white, black, asian, eastern european, whatever, then they should be the ones subjected to more stop and searches.
