Yes, traveling today can often be irritating, frustrating and even dangerous. But if you can afford travel no one should be held back indefinitely. The best resource I've run across is www.corporatetravelsafety.com. This website founded by a working policeman is so detailed it's a bit hard to process but the material is absolutely first rate.
You can find articles similar to Rick Steves, the veteran tourism guide, except the subject is safety and defense. For instance if you're going to Florence, Italy there are detailed descriptions of specific locations and particular risks or scams.
Do most people want to read all these descriptions? Certainly if you know your itinerary why not look and see what to be careful about?
