How the economic crisis has affected crime

Crime has always existed, in some countries more than anothers. It is not only about murders or situations that involve blood or death but when we are referring to crime, there are a lot of other types of crime that affect the welfare state. Petty crimes such as being burgled or being a victim of violence cause fear and insecurity in citiziens. In the last decades, it is well-known that as the economic crisis has increased, at the same time, security has decreased.
Obviously, every family needs to feed their children, buy a house and a car but when obtaining the simple things of life require very hard  work , is it (better: that) a good pretext to commit a crime? I do not think so, there is no need to hurt others that, maybe, are in the same situation.
