TMZ–The people closest to Lindsay Lohan aren’t the only ones who are alarmed at her condition — some police officers who routinely come in contact with Lindsay tell TMZ they have thought seriously about forcing her to get help. Cops who see Lindsay at her worst — late nights and early mornings when she needs assistance avoiding the paparazzi — tell TMZ they have been concerned about her “erratic behavior” and “attitude” — which have grown progressively worse over the last few months. We’re told during one of Lindsay’s crazier nights out recently, cops became so concerned they discussed taking her in for a 5150 evaluation. Cops decided against it because she didn’t meet all the criteria for a 5150 — they felt she could still take care of herself — though feebly. As we first reported, a professional who is extremely close to Lindsay fears she’s going to die if she doesn’t get help for substance abuse
