When I see videos on the internet all the time of criminals just walking into stores and grabbing whatever they want while the security guard looks on and does nothing because the police will side with the criminal if he touches them, it is perfectly valid to assume that crime is worse.
When the police do nothing to enforce the law I do not trust the statistics because they are based on reports to the police.
Maybe the statistics are right, over the whole city, but where I live, crime has gotten worse.
I noticed neither any crime or homeless at that time. But people now seem swear it has gotten to be a big problem.
How many videos have you seen on the Internet of stores just calmly going about business with no shoplifting going on? The number of videos on the Internet is not an indication of any overall trend. The stuff you're seeing makes it onto YouTube because they are outliers.
The measure of the perceived crime level in one's neighborhood isn't really dictated by stats or news, but your own and your neighbours lifes.
I know where I live is quite calm bar some occasional burglar, and I know it because I live in the place and talk to people everyday.
It's similar to Hans Rosling's comments about poverty in the 3rd world. It often sounds like poverty is increasing as time goes by, but if looking at statistics, overall poverty is decreasing and have been doing so for decades.
