Below are my improvised steps:
1. You will need 2 players for this glitch/exploit to start. One is you and other random or friend.

2. Host/Play adversary jobSiege Mentality IV

3, Job setting: 2 Rounds, clothing =Classic.

4. Invite friend or random to start the job.

5. If you start as an Attacker in round one choose Justice clothing.

6. When the job is fully loaded and you are in job wait for at least 30 secs, if you are in Cops outfit (Attacker) then click Start/Option and find a New Session.

7. This is optional step, applicable only if didn't start the job as Attacker (Cop). At first round you kill yourself by any means or ask your friend to kill himself to end this round and when the second round is loaded, now its your turn as an attacker (Cop) wait for at least 30 secs then click Start/Option and find a new session

.8. When the New session is fully loaded you will see aBatonin your hand that means you are on right path, pull your phone select Quick Job and join Capture Job. Wait till the capture job to load and start (unfortunately it needs players to start a job). Here no setting are required. Once you are in capture job, you will be in Cop's outfit, if not quit and restart again from step 1

.9. In capture job go to your Interaction menu and select accessories to change your glasses. Wait till the Orange save circle is fully done and after that wait 10 more seconds. No need to complete the capture job. Logout from PSN/XboxLive and login by again. It will display error message and put you in story mode

.10. From story mode go online, preferable Invite only session or any will work

.11. Once you are online you will be spawn in cop's outfit, go to clothing store and save your outfit in new empty slot. You are done.rying to get cop outfit
