Could you start a farm and be in Law Enforcement?

When I get older(I'm 15) I want to start a farm. Whether it be crops or animals I will need a suitable job to get me started. Could I be a local Law Enforcement Officer and still have time to care for my farm?Can I still live out the dream of owning and caring for my own farm?I've grown up around farms.I love them. My parents never owned a farm but we lived near them and I loved every bit of it.my granddad owned horses. My other dream is to be in Law Enforcement.I would love to wear that uniform and protect those that I love and know.
