I agree Single. The youth generation has become a liability. Granted, there are millions of decent law abiding, civil engaging youths in America, but there are many others who have grown up without a strong morale center. It may be generational, but the video games that portray gun violence, robbery, mayhem, mass murder is, IMO, taking effect on youth of today. They escape to another world and isolate themselves and then explode on the rest of us. Parents have a strong role to play in this evolution of the times. You would think that a parent would know if their son or daughter was building WMD in the basement or garage but it does seem to happen with regularity. These kids on bikes think they are just taking out their youthful energy without consequences or ignore them altogether. As stated, there are a couple of bad apples in the group that tags them all as corrupt. They have a sense to belong to a group right or wrong.
