This particular law [4] could be abused in several ways.
1. 8ft is from where "law enforcement activity is occurring". Officers will act assuming that this covers large areas, not just 8ft from the officer themself. Only later will courts get a chance to push back against this.
2. Nothing prevents a police officer walking closer to the person who is recording, pushing away the recording (or forcing them to stop as its now within 8ft.
3. The law says recording is illegal if interfering with the police or unsafe. Again, police will apply this to very wide circumstances.
