CDN_Stalker: That top photo and the middle one are H&K promotional photos, and in them the tape lets you know that the guns are not loaded and are only for show. You can always tell H&K promotional photos from real SWAT operater photos a number of ways. I think I picked this up from
www.hkpro.com. The two I remember are the yellow tape on mags and grips, and that the operators wear Oakley goggles.
