Hello!
ELS for for slots:
police
police2
fbi
noose
polpatriot
nstockade
pstockade

Is very unstable. If you really want to play with modded police cars on these slots try to use Non-ELS vehicles.
If you want to play with ELS without crashes create Addon vehicles, like police3, police4, policeb, policew. I am using these slots for my ELS vehicles - for now its the best way. + ELS support more those police slots:
EMERG1
EMERG2
EMERG3
EMERG4
EMERG5
EMERG6
EMERG7
(Remember to add new slot in _SLOTCONTROL in els folder)

If you want to create Addon vehicle:
In vehicles.img rename model to police3, police4 etc. (.wft, .wtd)
Then go to the:
Handling.dat - create new line for your vehicle
Vehciles.ide - ^
Carcols.dat - ^
Cargrp.dat - add your vehicle in the # POPCYCLE_GROUP_COPS
Then go to the LCPDFR.ini and add AdditionalCopCarModels=POLICE3;

That's it, you have new police addon vehicle in game!
