How come police officers do not deal with crimes even though they have spare time???

If you're wondering why there's more crimes it's mostly because after a day of patrolling and dealing with stuff , they don't check for things that are suspicious on their way back (sometimes they do it .) Now it's just totally weird they are driving slow like a normal car speed and they don't notice something TERRIBLE happening , isn't it guys? But it's alright if they are driving faaaast to the police station for a triple important meeting and a gang wobbles into view but they don't see . (someone else might deal with it if we're lucky.)

To fix that , we have 2 choices , here they are .

• a dashcam (one at every window, but not at the front window.) or
• a camera line and a tablet or a iPad to see what is happening from the camera line view. (one at every side , but not at

Tell me your choices , i am eager to see .( i am on this website every time/day so i will get to check them . Have fun !!! )
