And while my fellow Britons are smugly touting Background checks as the answer may I remind them of the fully background checked women caught fiddling with young children in that Portsmouth Nursery? CRB only goes so far. All they really mean is you have a clean record,plenty of people dont get caught,no record.
No checking system will ever be perfect, people will slip through, mistakes will be made, only a person's past can be checked, not their future. However, any
system is better than none at all, doing anything is better than doing nothing: Poland has no checking system at all and is doing nothing at all to introduce one. This will have entirely predictable results.
To the tit who seems to think only expats are a threat, yes,of course,no Pole would ever do anything perverted would they......
Of course not. And if a Polish man's sperm is found inside a rape victim who has been very nearly beaten to death, why that is simply proof of an anti-Polish plot!
