If you mean with respect to crime, then no. Hong Kong has one of the world's lowest crime rates and what violent crime does exist, is typically targeted (e.g. organized crime, domestic disputes).
For example, the intentional homicide rate is 0.2 per 100,000 people, vs 4.8 in the US. [1]
I have lived here for many years, and I can't think of any area that i would feel uncomfortable going at any hour of the day or night.
I feel so safe in Hong Kong that, by comparison, I feel unsafe almost everywhere else.
Even though local people bemoan the rise of petty crime and violence compared to the old days, it's still not an issue and I feel safe going anywhere, at any time of the day or night. There is no street violence, no street gangs (although there is organised crime of which the Triads are the most famous of course), not even much graffiti (there is a bit of it, but it's mostly artistic/social expression from underground artists rather than used for turf wars).
Actually I have not even ever seen anyone jump over a turnstile to avoid paying a fare.
I grew up in Hong Kong and way back in the early 90s, if you hit the MTR (the underground/metro/subway system) turnstile hard enough with your thigh as you were walking through, it would give way, so you could basically travel for free. No jumping required, which might explain your observation!
I think they've changed them now, and I think it only ever applied to the turnstiles on the Kowloon side of the line.
