Everyone is going to react to an extreme level to a security issue - such as a streaker coming on the field.
I can remember the famous photo, in the seventies at Twickenham, I think, of a policeman covering the genitals of a streaker with one of those old-fashioned police helmets.
Everyone looks reasonably genial about the situation.
Today, security guards react like the Secret Service around the President. You're going to get tackled really hard, as we've already seen. In some photos, Napier streaker Rose Kupa looks like she's getting coat-hangered.
Sooner or later, a streaker is going to get badly hurt.
You won't get any sympathy from me. If you want to streak, strip off and run down a main street if you need to get it out of your system - or off your "bucket list", as I believe was the case with Kupa.
The All Blacks - and any sporting team - deserve to have 80 minutes of absolute focus on the game, and feel completely safe doing so. New Zealand shouldn't be at the level of having 2m-high chain-link fences around the perimeter, like in England. Streakers are thankfully rare, and the mentality may be light-hearted, but the game has moved on.
