In the Maryland trial of the Washington area sniper John Muhammad, his former colleague turned prosecution witness John Lee Malvo yesterday confirmed in court what had been guessed from their shooting technique: they were using IRA methods from Northern Ireland --
[CNN] Malvo, 21, described how Muhammad modified an aging Chevrolet Caprice to allow a person to crawl into the trunk and shoot.
He told jurors that Muhammad was the triggerman in the first six killings, all but one of which took place in Montgomery County, Maryland.
Their tactics came from an Irish Republican Army training manual, said Malvo, testifying for prosecutors after agreeing to plead guilty to murder charges in Montgomery County.
It's not clear how Muhammad got the manual. Muhammad is a US Army veteran, so it's not inconceivable that the IRA methods are studied in military circles in the USA.
