About 10 years I lived in a flat locally with another flat below having a shared letter box.
Some dubious people moved in for about 6 months. There were 2 of them but there were numerous letters from the benefit office , about 9 names , sending our hard earbed money to these crooks.

When they left letters continued so took them into F H Job Centre and pointed out there failings but they did not seem to care.

Surely these crims were claiming for many different ID's. If we all had ID Cards or all had DNA on national data base any duplicate claims would show up at once.

Come on HMG I am sure most honest persons would have no problem with ID Cards or DNA . Think DNA would be cheaper and more reliable.

I will imagine I will now get a torrent of abuse , but that's life.
