Statistically, pretty much all batteries are safe. Millions and millions of batteries pass through airports, train stations, shopping centers, etc. daily, and nothing happens. And then one of them catches fire, and it's in all the media. Compare this to eg. car crashes,... you probably know more people who've been in a car crash compared to people who've had batteries explode. ...on the other hand, we've banned liquids on planes because of an even rarer event.
