As a general statistic, if you google it, you'll know the crime rate has been increasing in the last few years. They either fell into dumb ears or they make up by letting the criminals out.
What's the point?
The Government (or the Police) have of course no right to manipulate the data - in Sweden more or less all data is publicly available, and manipulation of crime statistics would be something very noteworthy (and likely to cause a big scandal).
And finally, if you google it, you'll know that crime rates have been decreasing in the last few years (few years meaning 2-3, and looking at all categories of crimes). Over a 10 year period, some categories of crimes have risen (at least the number of reported crimes have risen), and others, like homicide have markedly declined.
Obviously, so does the legal system but people are smart enough to find loopholes and find a way to do.
