You can have other kinds of security without necessarily having the strip search machines. For example, basic checks like going through a metal detector or passing sniffers for explosives or other undesirable substances have proven to be relatively reliable, and do not cause significant concerns relating to either health or privacy in the way that various body scanning technologies do.

In any case, I am at a similar risk of someone unhinged killing me and hundreds of other people every time I get a local train into the city, which requires no security checks at all. This was, unfortunately, demonstrated in the 7 July attacks in London, and I personally know people who were caught up in those attacks and hurt so I'm the last person who's going to be flippant about that possibility. I still feel just fine about my survival chances getting on a train, though. More people get hurt and killed on our roads most weeks than died in the 7/7 attacks, and those were more than a decade ago and haven't been repeated since.
