The worse the budget situation gets, the more patrols there will be. For a while this will be both traffic enforcement and DUI/OMVI patrols.
As the economy moves more toward total break-down, the police will move more toward their original purpose: to protect the State's interests, which government refers to as "keeping the peace".
No matter how bad the situation gets, be it for revenue purposes or just to control the populace, there will be more patrols of all kinds in the future.
And anybody who has done the math knows that there is a whole culture of jobs and dependent economy built on both Traffic and OMVI tickets. Just look at the cost of your speeding fine on your ticket and compare that to the add-on of court costs that you pay even when admitting guilt and mailing in your payment. Look at the fines, court costs, schooling/rehab and long-term insurance costs associated with just a first-time OMVI offense.
Ohio is ranked the forth worst state for speed traps in the US. To reiterate, it will get worse as the times do...
I drove to WVa the other day, spent 35 miles on 33 in Ohio and saw 10 troopers and 2 sheriffs. That's one every 2.9 miles. In 145 miles through WVa on Rt.77, I saw one trooper and one sheriff.
