I have a better suggestion Sir. Same is cost effective and will create many job opportunities.
I think the Federal Government can purchase a lot of drones, maybe a million or two to cover and monitor real time traffic on every major roads include train tracks across the Federation....
Employ a lot of youths to handle these drones from selected command centres across the country.
These youths will work on shifts of 6 or 8 hours per drone 24/7.... (Let the repentant 'yahoo boys' occupy night shifts, they barely sleep anyways)
Their task is simple: zoom or move your drone to cover your section of the road maybe a kilometre or 2 at most.
An employee have a window of 5 minutes to go back and forth on your section of the road.
In the event of an eventuality like a kidnapping. Call for back up drones to join in the tracking of this elements while you report to the Command centre. The command centre immediately deploys your well equipped and specially trained anti-kidnapping JTF to be on their trail. Within 4 hours max, victims are reunited with their families.
I believe in a year or 2, these criminal elements will be discouraged from this ugly 'business'
