Would you let your children wander a red light district?

Some of our children's friends were given tablets for Xmas and it just came to light that some of them still have no parental control software installed. The analogy here is: would you let your children wander a red light district? They would certainly see inappropriate things by accident, and older ones might be tempted to indulge their natural curiosity. It doesn't take long to install something like K9 from the Android Play store, or from the Apple Appstore, to make sure their web browsing is suitably filtered.
