Extremism in certain mosques was ignored by the authorities and government negligence aided and abetted the problem. I can accept brainwashed as being an outcome,but words like grooming betray an ignorance of the meaning of the word, that has strictly sexual connotations. To what extent they were the young innocents led astray as beloved by the majority of those here attempting the moral high ground is a total unknown at this stage.

Britain had no role during the Spanish civil war but the release of recent records show what a close eye British intelligence kept on the potential volunteers at the ports, and how unwilling they were to prevent their departure. The British government was loth to use the 1870 Foreign Enlistment Act, fearing that if a case came to court it could not secure a conviction, and would face political embarrassment.
the returning British veterans received a tumultuous reception from friends, families and supporters, they faced grave suspicion from many within the government and security services who suspected that the veterans had been ‘imbued with revolutionary sentiments’.

Although it was recognised that there was little chance of successfully prosecuting any volunteers under the archaic Foreign Enlistment Act, many veterans found their attempts to volunteer for the armed forces in the Second World War blocked, or encountered discrimination in their workplaces for many years to come.
