I don't think most reasonable people want police to be personally liable for every single thing they do, but neither do they want them to have broad and complete immunity from the law. The answer is somewhere in the middle, where police are protected in certain situations, but do still need to think about the consequences of their actions.
I didn't do more than 30 seconds of research here so I won't claim to be an expert, but according to the report in [1], Texas is the state with the fifth highest medical bills, "highest percentage of adults who have chosen not to see a doctor at some point in the past 12 months due to cost", and "the highest percentage of children—14.9%—whose families struggled to pay for their child’s medical bills in the past 12 months".
Some of that is no doubt Texas refusing to expand Medicaid under the ACA, but also "the study found that Texas exhibits the fourth-highest annual premium for both plus-one health insurance coverage ($4,626) and family health insurance coverage ($7,051.33) through an employer," so "a good deal cheaper" doesn't really seem an apt descriptor.

We're legitimately at the point where mcdondalds cashiers have higher standards for accountability and behavior than the police. Just sit back and really, really think about that. And, to top it off, there's droves of people like yourself who are so accustomed to such a broken system that they legitimately believe it couldn't be done any other way - even though there are minimum wage workers working under stricter rules!
