Is there a way of removing 'View' from event reports
This is a bug.  In replicating it I saw it was easy to fix, so I did.

See the bug report here: https://issues.civicrm.org/jira/browse/CRM-19782

If you don't want to wait for this to be incorporated, you can patch your CiviCRM using the fix here: https://github.com/civicrm/civicrm-core/pull/9546/files
