How to delete pictures permanently from Photos app in my entire mac?

Within the Photos app for OS X you cannot delete a picture permanently from your Mac.

(I have imported my existing iPhoto library when I migrated to Photos on 10.10.3)

When I delete a picture from Photos. Photos then puts the picture in a trash bin that is hidden in the File button on the task bar - "Show Recently Deleted". When you select this it then shows all of your deleted pictures you selected in Photos. If you then select to "Delete All" it asks you again are your sure and you click ok. Photos then cannot see these photos. BUT IT DID NOT DELETE THEM FROM YOUR MAC!

I then opened iPhoto, found the photos that I deleted inside the Photos app and viola they are still there, (these are not thumbnails!) these are the exact picture. HOW DO YOU VERIFY? In iPhoto if you select the picture then go to File - "Reveal in Finder" it will show that the picture you THOUGHT you deleted in Photos, is still there in the Master folder in your library!!

FYI there is no way in Photos to find the file location, very sneaky because the app is not deleting these files. This very frustrating coming from Apple who is pushing thinner profiles so SSD's with very limited storage, to give you the assumption that you are actually deleting these photos and videos when in fact you are not.

Question again is...

How to delete pictures permanently from Photos app in my entire Mac?

Does anyone have a solution other than don't use Photos.

This question was asked and solved already but I have verified that "Delete All" in the hidden trash can in Photos does in fact not delete from your disk space! Have a video on my YouTube Channel iTJMacattack that shows this issue - for proof.

Please real help and a solution!!

Thanks,
