It is again essential that, if data matching is to be carried out, all of the data that is to
be matched is kept up to date, so that people are not put under suspicion due to
inconsistencies between outdated records. The burden of keeping data up to date
should not fall on the individual, except where that duty already exists. If the Home
Office initiates an investigation, it should first verify the data that led to the suspicion.
Again there should be statutory compensation for people damaged by investigations
that prove groundless – otherwise there is a risk that the investigations themselves
can be used as a form of oppression – as IRS investigations in the USA are
sometimes seen to be.
