It is relevant. Flares, amongst other things, are not allowed, but they got in. Bag searches were being done, perhaps hapazordly. So if flares didn't get picked up what other things could have sneaked in. If you recall a few years ago someone got past security at the Manchester Arena, left a bag with a bomb in it and a large number mostly kids got killed. If security is lax anything could go on, not only bombs....machetes, you name it, it could happen.
