Gary McGraw, Brian Chess, and Sammy Migues interviewed nine executives running top software security programs, and wrote an article for InformIT. Some results showed that we are still not doing enough, even at our best. Some showed that some of the things we stress most heavily are actually wrong. The article is summarized in a bullet list.
I am not able to see why tr is behaving surprisingly strange.
I am pasting the commands and output. see if anyone can explain the mystery.

RUNCON(1) User Commands RUNCON(1)NAME
runcon - run command with specified security context
SYNOPSIS
runcon CONTEXT COMMAND [args]
runcon [ -c ] [-u USER] [-r ROLE] [-t TYPE] [-l RANGE] COMMAND [args]
DESCRIPTION
Run COMMAND with completely-specified CONTEXT, or with current or transitioned security context modified by one or more of LEVEL, ROLE,
TYPE, and USER.
If none of -c, -t, -u, -r, or -l, is specified, the first argument is used as the complete context. Any additional arguments after COMMAND
are interpreted as arguments to the command.
Note that only carefully-chosen contexts are likely to successfully run.
Run a program in a different security context. With neither CONTEXT nor COMMAND, print the current security context.
