Warren Gatland says he does not know what the fuss is about regarding training ground security screens being used at the World Cup.
A screen has been sited around England's training pitch at the squad's Pennyhill Park camp in Surrey following completion of their three warm-up games for the tournament, and reports state there is also extra security on patrol.
England boss Stuart Lancaster played down the threat of espionage, pointing out that opponents would glean far greater insight from watching video footage of England's matches rather than training.

And Wales head coach Gatland said on Tuesday: "I don't see what the issue is about this. It was done in 2011 (in New Zealand).
"Every (World Cup) venue in 2011 had 12-foot high fences around every training venue, so I don't know why people have made an issue about England being paranoid about it.
"It's just part of World Cup policy. It's not just security, it's just stopping people walking in off the street and it helps keep the venue secure. That's what happened in 2011."
Wales are currently training at their usual base in the Vale of Glamorgan, although they will relocate to Aviva Premiership club London Irish's new facilities to prepare for World Cup pool clashes against England and Australia at Twickenham on September 26 and October 3, respectively.
"We are a little bit different in our (Vale) training ground because it's a little bit more private.
"We are pretty private where we are, and I don't think there is a point in putting a screen around our ground when you can stand up on the hill and look straight into it!"
