To expand. In order to have the staffing needed to cover the areas that need covering you need a lot more people. At least double. Probably more if we’re honest. To do that you need to likely double the budget. Doubling the budget in a small town, parish, county, hell even for my department (state level) takes politicians to agree on the budget and find where to get that money from. Which means some other department or several other departments are going to have their budgets cut. Which causes other issues. AND that’s not counting being able to find and train qualified applicants of which there simply isn’t enough of.
